Defining Field of View
An adjustable
rectangular aperture
(or diaphragm) precisely defines the region of interest reaching the camera
sensor. This region is then reflected by both internal mirrors within the unit and dichroic mirrors placed in the
light paths to project this identical region into four quadrants. *
* Please note, the MultiSplit has been designed specifically to generate four images projected into quadrants –
the internal mirrors are not designed to be used in any other format (e.g. for two images side by side, or a single
full field ‘bypass’ image)
1.
Slide the two
aperture adjusters
(one horizontal, the other vertical) to define your region of interest.
2.
This region can be locked in place once alignment is complete by turning the aperture handles.
3.
Once your camera has been mounted following initial alignment, the aperture edges should be in sharp
focus in your image when partially closed. If not, please contact us ([email protected]) for further
advice and we will be happy to advise depending upon your hardware setup.

Filter cubes and cradles
The MultiSplit is supplied with three labelled calibration cubes to aid setup, each containing a 50% / 50% mirror.
Two cube cradles are also supplied and are essential to house cubes 2 and 3 at a 90-degree angle within the unit.
