Description

Notch Filters are Optical Filters that selectively reject a portion of the spectrum, while transmitting all other wavelengths.They are used in applications that require deep blocking of a narrow wavelength range, while offering broad transmission of the other wavelengths.

Applications

● Raman spectroscopy

● laser-based fluorescence instrumentation

● confocal or multi-photon microscopy

Benefits

● High transmittance

●deep reflection   

●narrow rejection bands
