Product Description

Description

Notch Filters are referred to as band-stop or band-rejection filters that selectively reject a portion of the spectrum, while transmitting all other wavelengths. The filters are used in applications as Raman spectroscopy, Laser-based fluorescence instrumentation, or other life applications.
