• Excellent UV Transmission Properties
• No Packing Fraction Loss
• Higher Overall Transmission than Glass Bundles
Our line of economically priced liquid light guides are ideal
for visible
and ultraviolet
illumination
requirements.
Unlike
glass light guides, liquid guides do not suffer from packing
fraction
losses–
spaces between
fibers
that cause reduced
coupling
efficiency (see diagram).
These liquid
guides cut off the near infrared
spectrum,
yielding
both optimum
transmission
for visible
applications
and smaller bandpass for higher contrast
color
images.
Reduced long-wavelength
transmission
results in slightly
bluer,
higher
color
temperature
output. Repeated
handling
of liquid light guides won‘t result in the efficiency reducing breakage
typical
of glass bundles.
Liquid light guides use quartz windows to seal in non-toxic transmissive
medium.
