CARV II Confocal Imager Light Path
Arc Lamp
: The light source is an EXFO X-Cite 120W Hg/metal halide lamp
which delivers light to the CARV II via a 1.5 M EXFO liquid light guide. The
liquid light guide delivery system produces even illumination and eliminates the
need for arc lamp alignment. The lamp has typical Hg arc spectral characteristics
and has a life of 1200 hours.
Shutter
: The illumination shutter can be controlled via the touch pad controller
or via RS232 commands (software control).
