Notch filter

产品详细

Brand: Xinzhao

Model: XZ-Mirror

Standard: US military standard

Introduction: Notch filter, also known as negative filter, is a light cutoff in a certain wavelength band, and both ends of the wavelength band are transmitted, and the curve graph is a concave filter. The notch filter provided by Xinzhao has the characteristics of high cut-off rate in specific bands, high transmittance in other bands, flat transmission curve, and small ripple coefficient.

And can provide special customization according to requirements, and the customization cycle is short.

In some Raman applications, a notch filter is used to block the excitation laser wavelength while transmitting the Stokes and anti-Stokes signals to the detector.
