Pinhole block


The A11027 is a holder block for mounting a pinhole. The screws can be used to adjust the pinhole's position in the XY directions. The built-in lens collimates the light that passes through the pinhole and converges the light on a photodetector.
There is a base attached to the holder block through the M3 screw holes in the bottom of the block. If necessary, this base can be removed and re-attached to the side of the block.

Extended example of microscope

Connecting the A11027 pinhole block to the C-mount port of a microscope configures a confocal optical system. Light passing through the pinhole is collimated by the lens in the block and is efficiently guided to the PMT module.
