Wavelength Pass or Short
Wavelength Pass
The terra-Q family consists of the terra-Q 100,
terra-Q 50, terra-Q 25, long wavelength pass and
short wavelength pass filter products. These filters
form the basic building blocks for a wide range
of optical filtering products for dense wavelength
division multiplexing (DWDM) optical systems.
The terra-Q family is based on time-tested thin-film
interference filter technology, the standard by
which other filter technologies are measured.
