Chapter 2 Overview
2.1 Introduction
These two position high speed flippers have been designed to flip a lens, filter or other
optical component into and out of an open beam.
The flip action is controlled by a button on the top of the unit, via the remote handset
included, or via a control PC. The flipper position toggles 90° between vertical and
perpendicular with each button press. The unit has two SMA connectors, marked
DIG I/O 1 and DIG I/O 2, for use in applications requiring an external or remote trigger,
e.g the remote ha ndset. The trigger is a button p ress or a TTL logic pulse, which
toggles the flipper position. The rear face of the unit features an array of vent holes to
aid cooling.
This small (70 mm x 30 mm x 30 mm) unit is powered by the included 15V power
supply. It is shipped with a 1.5 m (59.0”) USB cable.
The MFF101(/M) is supplied complete with our LMR1 (/M) Ø1" optics mount, while the
MFF102 is shipped with the LMR2(/M). Other holders in the LMR range are
compatible, up to a maximum diameter of 50.8 mm (2”). The flipper mount is ideal for
many optics, including mirrors. When used with a mirror, please note that the unit is
not recommended for applications requiring better than 100 µrad beam stability.

2.2 APT Software Overview
2.2.1 Introduction
As a member of the APT range of controllers, the MFF sreies Filter Flippers share
many of the associated software benefits. This includes USB connectivity (allowing
multiple units to be used together on a single PC), fully featured Graphical User
Interface (GUI) panels, and extensive software f unction libraries for custom
application development.
The APT software suite supplied with all APT controllers, including the MFF series
filter flipper, provides a flexible and powerful PC based control system both for users
of the equipment, and software programmers aiming to automate its operation.
For users, the APTUser (see Section 2.2.2.) and APTConfig (see Section 2.2.3.)
utilities allow full control of all settings and operating modes enabling complete ‘out-
of-box’ operation without the need to d evelop any further cu stom software. Both
utilities are built on top of a sophisticated, multi-threaded ActiveX ‘engine’ (called the
APT server) which provides all of the necessary APT system software services such
as generation of GUI pan els, communications handling for multiple USB units, and
logging of all system activity to assist in hardware trouble shooting. It is this APT
server ‘engine’ that is used by software developers to allow the creation of advanced
automated positioning applications very rapidly and with great ease. The APT server
is described in more detail in Section 2.2.4.
Aside
ActiveX®, a Windows®-based, language-independent technology, allows a user
to quickly develop custom applications that automate the control of APT system
hardware units. Development environments supported by ActiveX® technology
include Visual Basic®, LabView™, Borland C++ Builder, Visual C++, Delphi™,
and many others. ActiveX® technology is also supported by .NET development
environments such as Visual Basic.NET and Visual C#.NET.
ActiveX controls are a specific form of ActiveX technology that provide both a user
interface and a programming interface. An ActiveX control is supplied for each
type of APT hardware unit to provide specific controller functionality to the
software developer. See Section 2.2.4. for further details.

Chapter 2
2.2.2 APTUser Utility
The APTUser application allows the user to interact with a number of APT hardware
control units connected to the ho st PC. This program displays multiple graphical
instrument panels to allow multiple APT units to be controlled simultaneously.
All basic operating parameters can be altered and, similarly, all operations can be
initiated. Settings and parameter changes can be saved and loaded to allow multiple
operating configurations to be created and easily applied.
For many users, the APTUser application provides all of the functionality necessary
to operate the APT hardware without the need to deve lop any further custom
software. For those who do need to further customise and automate u sage of the
controller (e.g. to implement a positioning algorithm), this application illustrates how
the rich fun ctionality provided by the APT ActiveX server is e xposed by a client
application. The complete Visual Basic source project is provided as a useful aid to
software developers.
Use of the APT User utility is covered in the PC tu torial (Chapter 6) and in the
APTUser online help file, accessed via the F1 key when using the APTUser utility.

7
MFF101 and MFF102 Motorized Filter Flippers
2.2.3 APT Config Utility
There are many system par ameters and configuration settings associated with the
operation of the APT Server. Most can be directly accessed using the various
graphical panels, however there are several system wide settings that can be made
'off-line' before running the APT software. These settings have global effect; such as
switching between simulator and real operating mode, associating mechanical stages
to specific actuators and incorporation of calibration data.
The APTConfig utility is provided as a convenient means for making these system
wide settings and adjustments. Full details on using APTConfig are provided in the
online help supplied with the utility.
Use of the APT Config utility is covered in the PC tutoria l (Chapter 6) and in the
APTConfig online help file, accessed via the F1 key when using the APTConfig utility.

Chapter 2
2.2.4 APT Server (ActiveX Controls)
ActiveX Controls are re -usable compiled software components that supp ly both a
graphical user interface and a pro grammable interface. Many such Co ntrols are
available for Windows applications development, providing a large range of re-usable
functionality. For example, there are Controls available that can be used to
manipulate image files, connect to the intern et or simply pro vide user in terface
components such as buttons and list boxes.
With the APT system, ActiveX Controls are deployed to allow direct control over (and
also reflect the status of) the rang e of electronic controller units, including the MFF
series filter flipper. Software applications that use ActiveX Controls are often referred
to as 'client applications'. Based on ActiveX i nterfacing technology, an ActiveX
Control is a language independent software compo nent. Consequently ActiveX
Controls can be incorporated into a wide range of software development
environments for u se by clie nt application developers. Development environments
supported include Visual Basic, Labview, Visual C++, C++ Builder, HPVEE, Matlab,
VB.NET, C#.NET
and, via VBA, Microsoft Office applications such as Excel and Word.
Consider the ActiveX Control supplied for the filter flipper.
This Control provides a complete user graphical instrument panel to allow the stage
to be manually operated, as well as a complete set of software functions (often called
methods) to allow all parameters to be set and operations to be automated by a client
application. The instrument panel reflects the current operating state of the unit to
which it is associated (e.g. such as filter position). Updates to the panel take place
automatically when a user (client) application is making software calls into the same
Control.

9
MFF101 and MFF102 Motorized Filter Flippers
The APT ActiveX Controls collection provides a rich set of graphical user panels and
programmable interfaces allowing users and client application developers to interact
seamlessly with the APT hardware. Each of the APT controllers has an associated
ActiveX Control and these are described fully in system online help or the handbooks
associated with the controllers. Note that the APTUser and APTConfig utilities take
advantage of and are built on top of the po werful functionality provided by the APT
ActiveX Server (as shown in Fig. 2.2).
Fig. 2.2 System Architecture Diagram
Refer to the main APT Software online help file, APTServer.chm, for a comple te
programmers guide and reference material on using the APT ActiveX Controls
collection. Additional software developer support is provided on the ‘Support’ tab in
the Downloads section of our website.
2.2.5 Software Upgrades
Thorlabs operate a policy of continuous product development and may issue software
upgrades as necessary.
The latest APTServer software version is available from the dowmloads section of
www.thorlabs.com.

5) Go to Services/Downloads at www.thorlabs.com and download the APT software.
6) Run the .exe file and follow the on-screen instructions.
4.2 Electrical Installation
4.2.1 Connecting To The Supply
Caution
If your PC becomes unresponsive (e.g due to an operating system problem,
entering a sleep state condition, or screen saver operation) for a prolonged
period, this may interrupt communication between the APT Software and the
hardware, and a communications error may be generated. To minimize the
possibility of this happening it is strongly recommended that any such modes
that result in prolonged unresponsiveness be disabled before the APT
software is run. Please consult your system administrator or contact Thorlabs
technical support for more details.
Caution
Some PCs may have been configured to restrict the users ability to load
software, and on these systems the software may not install/run. If you are
in any doubt about your rights to install/run software, please consult your
system administrator before attempting to install.
Ifyouexperience any problemswhen installingsoftware, contact Thorlabson
[phone] and ask for Technical Support.
Warning
The unit must be connected only to a 15 V DC supply. Connection to a
supply of a different rating may cause damage to the unit and could result
in injury to the operator.

4.4 Verifying Software Operation
4.4.1 Initial Setup
1) Run the APTUser utility and check that the Graphical User Interface (GUI) panel
appears and is active.
Fig. 4.1 Gui panel showing jog and ident buttons
2) Check that the corre ct stage type and se rial number are displayed in the GUI
panel.
3) Manually position the mount away from its end stop, then click the ‘Position 1’ or
‘Position 2’ button. The ‘Moving’ LED is lit while the move is in progress, then the
LED in the position button is lit to show that thye move is complete.
Follow the tutorial steps described in Chapter 6 for further verification of operation.
Note
The 'APT Config' utility can be used to set up simulated hardware
configurations and place the APT Server into simulator mode. In this way it is
possible to create any number and type of simulated (virtual) hardware units in
order to emulate a set of real hardware. This is a particularly useful feature,
designed as an aid to application program development and testing. Any
number of 'virtual' control units are combined to build a model of the real
system, which can then be used to test the application software offline. If using
real hardware, ensure that Simulator Mode is disabled. If using a simulated
setup, enable Simulator Mode and set up a ‘Simulated Configuration’ - see
Section 5.4. or the APTConfig helpfile for detailed instructions.

17
Chapter 5 Operation
5.1 Manual Operation
The Filter Flipper offers a fully featured motion control capability including Transit
Time and I/O Configuration. When the unit is connected to the PC, these parameters
are automatically set to a llow “out of the box” operation with no further “tuning”
required. However, further adjustment is possible via the APT Server software - see
Chapter 6.
The flip action is activated manually by a button on the top of the unit, or by handset
supplied.
The unit features two SMA connectors, marked DIG IO 1 & DIG IO 2. A TTL trigger
input (configured in the Settings panel - see Section 6.3.) causes the flipper to toggle
to the next state. If the user button or another trigger signal comes in before the end
of the move then the flipper will ignore the demand until the current move is complete.
5.2 PC-Base Operation
5.2.1 Introduction
The following brief tutorial guides the user thro ugh a typical series o f moves and
parameter adjustments performed using the PC based APT software. It assumes that
the unit is el ectrically connected as described in Section 4.2. an d that the APT
Software is already installed - see Section 4.1.
Warning
When the unit is powered up, do not move the flipper arm by hand.
Notes
If power is removed, the unit may remain in the same position, or due to
gravity, may move to the lower limit.
The external DIG IO connectors can be configured as input or output to accept
various different signal types. A particular IO configuration can be ‘persisted
(saved) within the unit for future use when operating in Stand Alone mode
without a control PC - see Section 6.3. for more information.
Warning
As the unit is raised and lowered, items can become trapped in the
mechanism. During operation, keep fingers, clothing and tools away from
any moving parts.
When the unit is powered up, do not move the flipper arm by hand.

5.2.2 Using the APT User Utility
The APT User.exe application allows the user to interact with any number of APT
hardware control units connected to the PC USB Bus (or simulated via the APTConfig
utility). This program allows multiple graphical instrument panels to be displayed so
that multiple APT units can be controlled. All basic operating parameters can be set
through this program, and all basic operations can be i nitiated. Hardware
configurations and parameter settings can be saved to a file, which simplifies system
set up whenever APT User is run up.
Fig. 5.1 Typical APT User Screen
1) Run the APT User program - Start/All Programs/Thorlabs/APT User/APT User.

MFF101 and MFF102 Motorized Filter Flippers
5.2.3 Master/Slave Operation
If required, two flipper units can be wired in a master/slave configuration, such that a
demanded flip on one unit, also triggers the other unit to flip.
1) From the GUI panel of the Master u nit, click the Settings button to display the
settings panel.
2) Make parameter settings as follows:
Digital I/O Pin 1
Operating Mode: Input: Toggle Position
Digital Signal Mode: Button Input
These settings set the Master unit to flip the optic position, each time the button is
pressed.
Digital I/O Pin 2
Operating Mode: Output: In Motion
Digital Signal Mode: Logic Level Output
These settings set the Master unit to output a logic high signal on DIG I/O 2 while
the flipper is in motion.

20 HA0305T Rev H Jan 2017
Chapter 5
3) From the GUI panel of the Slave unit, click the Settings button to display the
settings panel.
4) Make parameter settings as follows:
Digital I/O Pin 1
Operating Mode: Input: Toggle Position
Digital Signal Mode: Logic Edge Input
These settings set the Slave unit to flip the optic position, each time a Logic High
(5V) Edge is received on DIG I/O 1.
Digital I/O Pin 2
In the two unit master slave configuration, these settings are not used, though it is
recommended that the DIG I/O Pin 2 Operating Mode be set to an Output option
to avoid accidental triggering of the flip action.
5) Connect the DIG I/O Pin 2 terminal on the Master unit to the DIG I/O Pin 1 terminal
on the slave unit.
