Bright Input Over-exposure Protection Circuit for Intensifier

Bright Input (Over-Exposure) Protection Circuit

All VSI Image Intensifier Assemblies and Intensified Cameras running at less than 30 fps are equipped with our new bright input (over-exposure) protection circuit. The intensifier automatically turns off when input brightness is high enough to be harmful to the intensifier. The user has to manually reset the unit to resume operation. This allows the user an opportunity to adjust the input brightness.

This feature is not installed in intensified high speed cameras or intensifier assemblies for high speed cameras. Nor is it built into 3ns gated, MHz gated or short burst gated units due to performance conflicts.

The bright input protection circuit is designed to help avoid accidental over-exposure. It does not warrant the intensifier from damages caused by over-exposure.
