VS4-1845XR

GEN III High Resolution Image Intensifier Assembly

FOR USE IN THE UNITED STATES ONLY

The VS4-1845XR Image Intensifier Assembly is an optically coupled high resolution GEN III image intensifier with the groundbreaking 2-Micron Pitch Micro-Channel Plate (MCP) for use in very low light level imaging.  The VS4-1845XR is coupled to user's camera through a high efficiency C-Mount lens.

The output format is adjusted for either a 2/3", 1/2" or 1" format.  An intensifier control module allows full computer control of the gain, gate, and gate delay of the intensifier through a RS-232 (serial port) interface.

The VS4-1845XR is designed for use in applications where rigorous quantification of the intensity and location of lower light level objects are required as in scientific applications.
