3.2) Centring the Bypass Image
Once a rectangular region of interest has been defined, this image can then be centred in Bypass
mode.
1.
The XY controls for the Bypass image
are located on the
input port
of the OptoSplit.
2. Using the 1.5mm allen key provided, adjust each of the two controls in turn whilst observing
your single image on the camera. One control will result in a horizontal movement, the other
vertical.
3. Centre the Bypass image using an iterative approach with the two controls. A rectangular Re-
gion of Interest within your imaging software is useful as a reference tool to ensure the image
is centred and square.
4) Obtaining a split image
The predominant operating mode of two identical images projected onto each half of your camera
sensor is achieved by installation of a Cairn filter cube.
For initial setup, we recommend using the supplied Calibration Cube (with a 50% / 50% mirror)
and a focussed image of a graticule with transmitted light.
1. Slide the
Bypass / Split lever
to ‘Split’.
2. Install the calibration cube, by removing the magnetic
door cover
labelled REFLECTED PATH.
3. Insert the calibration cube, which has a magnetic fixing and will easily locate into place, with
the small handle facing outwards.
4. Replace the door cover.
5. Ensure the
rectangular aperture
is closed enough in both dimensions to see two distinct
images.
