STANDARD
BANDPASS (FIB) 10nm FWHM RANGE
These
Interference Bandpass Filters are used to isolate and transmit
a narrow wavelength that is required and block all other
wavelengths through reflection.
This
range of Interference Bandpass Filters consist of an all-dielectric
coating along with other coatings for additional blocking
and cemented together to form a stack. The individual filters
are scribed and mounted in rings, providing a labyrinth
epoxy edge seal for greatly extended life. Although these
are mounted, un-mounted types can be supplied at special
request. These Interference Bandpass Filters are all typically
3-7 cavity.
These
typical 3 Cavity Bandpass Filters are offered with center
wavelengths from 330nm to 2000nm. Offered every 10nm in
CWL from 330nm to 1000nm, and every 20nm / 50nm from 1000nm
to 1680nm and every 100nm from 1700nm to 2000nm. Blocking
is Metal-Dielectric from 200nm to Far IR (3000+nm).
