hsfc pro
Having a single optical input, this camera system comprises an image splitter unit, four intensified CCD camera modules with fast switchable MCP
image intensifiers and high resolution CCD image sensors. Each module
with its 12bit dynamic range and a high resolution CCD image sensor
( SVGA) features an excellent signal-to-noise-ratio and the ability of single
photon detection. Four high speed serial fiber optic data links connect the
system to the PC. It can be triggered externally by light or electrical input.

| image splitter |
four channels distribute 22% of total incoming light
to each module. The user can exchange beam splitter parts and mirrors to configure 1-, 2-, 3-, or 4
channel systems. All components are made in premium quality. The
image splitter cubes are placed in the infinite ray
path between the collimator lenses. The mirrors are
mounted on strong spring loaded holders to absorb
external shocks. Individual filters can be inserted in
filter holders on each module for spectral range selection.
