OptoMask
Fast Crop Mode
The OptoMask is an inline C-mount device with precise aperture control to enable high speed cropped mode imaging using a suitable EMCCD.
The OptoMask incorporates a fully adjustable large aperture adjustable field mask to enable high speed sub-region acquisition with suitable frame transfer cameras such as the Andor Ixon Ultra and Photometrics Delta ranges. For maximum flexibility we designed the OptoMask to enable an arbitrary rectangular region to be masked anywhere within the image plane and to allow rapid switching between a pre-determined mask and the full sensor.
All our OptoMask products use a single custom made achromatic triplet lens with anti-reflective coatings from 425nm to 875nm.
