Global Laser Cameo 1250 CW User manual

Thank you for purchasing a Cameo laser module. This module emits a red / infra red spot or
projection. You will have one of the following two versions.
1250 CW Cameo
1260 Gated Cameo
If you have any queries or require help when using the Cameo range please call us on +44(0)1495
212213 or contact your local representative.
The Cameo series is a miniature laser diode module that has a threaded barrel for easy bulkhead
mounting which also ensures good thermal contact between module and heat sink. This new
concept in laser module design allows a laser diode, an adjustable collimating lens and a drive
circuit to be incorporated within a body which is just 23mm long and all without compromising
the performance. The Cameo oers high output power stability with transient and polarity
protection, as well as electrical isolation between diode and case. It has a latching connector
that improves reliability.

2. Production Operation
B: 1260 Gated Version
Introduction
A common requirement for applications which use photo detectors, cameras and other non-
visual sensing is the ability to rapidly switch the laser output ON and OFF. Simply applying and
removingthesupplyvoltageisrarelysatisfactoryandincertaincasescanresultinthedestruction
of the module. This is because laser diodes are very sensitive to spikes and surges, which are
often the result of uncontrolled supply switching. To overcome this limitation, the 1260 Gated
Cameo has two additional inputs that are provided to control the output of the laser module in
a reliable and predictable way.
Control Input (Pin Three Yellow wire)
A logic LOW level turns the output completely OFF (≤5%). However, applying a logic HIGH turns
the laser ON after a control input delay. This sets the maximum rate at which the module can
switch fully ON and OFF. Bandwidth is ≥ 100Khz.
Enable Input (Pin Four Blue wire)
Some applications require a simple, slow speed ON/OFF Switching (such as an enable switch).
The 1260 series eliminates the requirement to provide an external switching device by providing
alogiccompatibleenableinput,capableofoperatingfromlowpowerlogicand micro-processors.
In this OFF condition, the module draws very little or no current and no light is emitted. The
logic input is Non-inverted.
Pin connections and functions
Connect the supplied 4 way JST connector to back of laser -
CW MODE:
To operate laser in CW mode the Red, Black, Yellow and Blue leads should be connected to the
following:
A: 1250 CW Cameo
To operate the laser, connect the input wires in the below conguration.
1. Red Lead: +3.3Vdc to +5Vdc
2. Green Lead: 0Vdc

4. Mounting & Heatsinking
The Cameo laser module is designed to be mounted via its threaded front barrel (M12X1 Thread)
ideally to a metal mounting bracket or bulkhead. To further assist mounting the module is
supplied with a nut which is tted to the front barrel. A tool to t a 15mm nut is required for
adjustment. The direct contact of the barrel to the mount helps to ensure heat sinking and
improve laser diode lifetime. To further improve reliability the barrel is isolated from the laser
diode supply voltage at all times. The case temperature should be kept within the specied
range at all times failure to do this could result in shortened lifetime or catastrophic failure. As a
guide, laser diode lifetime decreases by a factor of two (approx) for every ten degree increase in
operating temperature.
5. Safety & Classication
These modules are intended for incorporation into customer equipment. They are classied in
accordance with IEC60825 2007, which should be consulted prior to designing or using any
laser product. The following labels are supplied for attachment to the customer’s equipment,
but responsibility for compliance with the standard remains with the user.

7. Focus Adjustment
The focus of the laser can be adjusted by using the supplied focus key. Should you need to
adjust the focus please follow the instructions below:
1. Remove any external optics, where tted.
2. Insert focus key into laser barrel and align with focus control groves.
3. Turn the focus key until desired focus is achieved.
4. Replace the external optics if tted and rotate to achieve the desired projection.
