slits are used in spectral system, optical diffraction experiment etc.
OM-ws is a width adjustments slit of one adjustable blade.
The slit width ranges from fully closed to 5mm and slit
length is 20mm. Since it is one dimension adjustment, the
center of the slit moves with the changes of slit width
accordingly. An M6 threaded mounting hole at the bottom of
the slit is compatible with our mounting posts. And 4-M3
threaded mounting holes at the side of the slit allows the
slit attach to our optical plates through a specified plate
(Please refer to AS series for details).
