Notch filter
Notch filters are also called band-stop or band-reject filters. It can transmit most wavelengths, but attenuates light in a specific wavelength range (stop band) to a very low level.   Notch filters are the opposite of band-pass filters. Band-pass filters provide high pass-band transmittance and excellent out-of-band rejection characteristics, so that they only transmit light in a small wavelength range, while notch filters Only suppress light in a small wavelength range. High precision, consistency and stability are important characteristics of HB Optical filter products. Each piece of product will go through precise and strict factory inspection. A variety of sizes and center wavelengths are available, and product customization services can be provided.
