Glass notch filter

Glass notch filter

Notch filters are widely used in optical components in the fields of spectral detection and fluorescence imaging because of a special optical thin film structure that efficiently blocks specific narrow-band wavelength rays and allows high transmission of other wavelengths of light to achieve spectral separation and stray light elimination.

 

  • Product Details

Glass notch filter

 

Product Overview:

Notch filter is an optical element that can selectively and greatly attenuate the optical signal in a specific wavelength range, and let the rest of the wavelength light pass through smoothly to achieve optical signal separation, purification and background noise suppression.

Scope of Use:

(1) spectral analysis;

(2) fluorescence detection;

(3) laser systems.
