VS4-1845HS
Image Intensifier Assembly for High-Speed (>1000fps) Cameras
The VS4-1845HS is an Image Intensifier designed specifically for
High-Speed Cameras.
Applications Include:
Microscopy
Time
Resolved Imaging
Flow
Visualization
Combustion Research
Munitions
Studies
Particle
Imaging Velocimetry
and Other
Scientific High-Speed Imaging
Features:
Double
Intensifier for bright output required for High-Speed imaging
Extended
Blue Response from 350 to 900nm
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 C-Mount output
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.
