OptoMask OC

Fast Crop Mode

The OptoMask is an inline C-mount device with optically centred aperture control for high speed crop mode imaging. The OptoMask has been specifically designed to enable use of Optically Centered (OC) crop mode on Andor 897 and 888 cameras and lightspeed mode on the Photometrics Delta. This device uses a single achromatic triplet lens to minimise losses and incorporates a quick and convenient mechanism for adjusting the mask size from full chip to a few pixels with a single control. Preset markings are included to set useful frame sizes for both 1024 and 512 sensors.

All our OptoMask products use custom built achromatic lenses with anti-reflective coatings from 425nm to 875nm.
