1 Description
A SuperK SPLIT is a passive filter accessory for the SuperK laser series. A SuperK
SPLIT divides the super continuum spectral emission from a SuperK laser. A
SPLIT has two separate outputs, each outputs a subset of the original super
continuum beam source.
Figure 1 SuperK SPLIT general view
The diagram in Figure 2 shows one output channel consisting of a broadband
subset of the original super continuum wavelengths in the visible (VIS) and near-
infrared (NIR) range and the other channel consisting of a broadband subset in
the NIR and infrared (IR) range.
Figure 2 SuperK SPLIT functional view
Note: See Table 3 on page 29 for SuperK SPLIT model specifications.
Output options The SuperK SPLIT filter block may be combined with a SuperK CONNECT and
SuperK Fiber Delivery (FD) to form a Fiber Delivery System (FDS).
Additional filtering An External Filter Holder add-on can be fitted before any fiber coupling. Using
the holder any standard 1-inch filter can be placed in the beam path.

Features
Output Emission from both SuperK SPLIT output ports are free space beams. To deliver
the two bands of supercontinuum spectrum, a Fiber Deliver System (FDS)
consisting of dual SuperK CONNECT and SuperK Fiber Delivery (FD) accessories
can be fitted to the SPLIT.
Interlock The SuperK SPLIT is equipped with a safety interlock. The interlock inter-
connects with the SuperK laser’s interlock system. The interlock system is setup
to disable emissions immediately when the interlock circuit is broken, such as an
interconnected safety door switch. Refer to “Electrical Connections” on page 25.
Shutters As a safety feature, each optical output of the SuperK SPLIT is equipped with a
mechanical shutter. When the shutter is closed, it blocks all optical emission. The
shutters are manually operated by turning the shutter knob between the Open
and Closed positions as shown in Figure 3.
Figure 3 Output aperture shutters
Caution: When the laser outputs are not in use, NKTP recommends to CLOSE the
shutters.

Mounting holes
The two mounting holes (1) are designed to fasten the SuperK SPLIT to either
metric or imperial optical tables that have screw holes spaced at either 25 mm or
1” pitch.
NIR/IR output shutter
This shutter can be set to block or unblock the NIR/IR emission output aperture.
Turn the shutter to the “Closed” position to block emission. Turn the shutter to
the “NIR/IR” position to unblock emission from the aperture.

VIS/NIR output shutter
This shutter can be set to block or unblock the VIS/NIR filtered output emission
from the aperture. Set the shutter to the “Closed” position to block emission. Set
the shutter to the “VIS/NIR” position to unblock emission from the aperture.
Collimator release button and locking screw
SuperK laser outputs are provided with a barrel shaped collimator. When the
barrel is inserted into an SPLIT optical input receptacle, it is automatically
retained by a locking mechanism that securely holds the barrel in place. To
release the collimator from the input receptacle, press the Collimator Release
button (4).
Note: You can lock the collimator barrel in the optical input by tightening the col-
limator locking screw (5).
Optical apertures Optical apertures are located on the side panels of the SPLIT as shown in
Figure 5 and described in the following.
Figure 5 Optical Interfaces
Optical input aperture
The Optical input aperture is a receptacle that houses the output collimator of a
SuperK laser. The laser’s output collimator is inserted into the aperture until it
clicks and locks in place. To remove the collimator, press the release button. The
laser’s collimator barrel can be secured by tightening the lock screw.
The optical input includes an interlock switch. If a SuperK collimator is not
inserted in the input receptacle, the switch detects this and prevents emission
(refer to Figure 6).

VIS/NIR optical output aperture
This is a free space output aperture for the primary filtered emission.
NIR/IR optical output aperture
This is a free space output aperture for the visible emission.
Note: All output apertures include 4 screw holes for mounting, for example, a fi-
ber coupler such as an FDS consisting of a SuperK CONNECT and FD.
Electrical Interfaces The electrical interfaces are located on the same side panel where the optical
input aperture is located. Figure 6 shows the panel, all electrical interfaces are
located on the right side of the panel.

External bus port
The External bus port connects the accessory to a SuperK laser. SuperK lasers
connect to accessories using the NKTP External bus protocol. The bus carries
data communications, DC power and the interlock signal from the laser to any
accessories connected on the bus.
Optical input aperture
See “Optical input aperture” on page 16.
Bus through port
Connects additional accessories to the External bus in a daisy chain
configuration. A bus defeater must be connected to this port if no other
accessories are used with the SuperK laser. Without a bus defeater at the end of

the External bus daisy chain, the interlock loop circuit will be open and emission
disabled at the SuperK laser.
Status LEDs
The SPLIT includes three status LEDs as described in Table 1. The LEDs are
located on a side panel next to the External bus ports and shown in Figure 7.
The emission LED is lit ON RED when the connected SuperK laser’s emission is
enabled. When ON RED, laser emission is present at the primary and auxiliary
optical output ports.
Warning: If any of the SPLIT aperture shutters are closed, emission is blocked. The
position of the shutters does not affect the status of the emission LED, only the emis-
sion status of the connected SuperK laser.
