STANDARD
BANDPASS (FIB) 22-40nm 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 5 Cavity Bandpass Filters are offered with center
wavelengths from 400nm to 905nm. Blocking is Metal-Dielectric
from 200nm to Far IR (3000+nm).
