VS4-1845HS: Image Intenfier for High Speed Cameras (>1000 fps)

Image Intensifier Assembly for High-Speed (>1000fps) Cameras

The VS4-1845HS is a new Image Intensifier designed specifically for High-Speed Cameras. Based on the type of phosphor in the image intensifier, the VS4-1845HS comes in two versions: the VS4-1845HS-P43 for cameras operating up to 1000 fps and the VS4-1845HS-P24 for cameras operating over 1000 fps, up to 1 MILLION fps. Both versions use GEN III Image Intensifiers with over 50% quantum efficiency available:

Applications Include:

Microscopy
Time Resolved Imaging
Flow Visualization
Combustion Research
Munitions Studies
and Other Scientific High-Speed Imaging

Features:

Double Intensifier for bright output required for High-Speed imaging
Extended Blue Response from 350 to 900nm with over 50% QE at 500nm
Optional UV Response from 200 to 700 nm
Gating from 50ns and Gate Delay from 0 to 2ms or DC Operation
Negligible shading and geometric distortion
1/2", 2/3" or 1" camera format output
Standard C-Mount input and F-Mount output, which can be converted to C-Mount with an adapter
Computer Control of All Functions

The VS4-1845HS is pre-adjusted to work with an included computer control system operated from a GUI on the computer. It is all self-contained and requires no control unit. The GUI adjusts the Intensifier Gain, Intensifier Gate and Intensifier Gate Delay. The supplied software runs in all late versions of Windows™.

The VS4-1845HS was designed for use on high-speed cameras for scientific applications. There is no Automatic Gain or Gate control. The VS4-1845HS operates under the manual control of the user at all times. The output is strictly linear. The VS4-1845HS presents to a high-speed camera, with short exposure times, the bright output needed to expose the camera. The sensitivity of the VS4-1845HS and high-speed camera is a function of the sensitivity of the camera used. Higher sensitivity cameras will yield better low light level results.
