A filter with cutoff areas on both sides of the transmission band of the spectral characteristic curve is called a bandpass filter, which is often used to transmit a part of the spectrum while cutting off all other wavelengths. Bandpass filters are an important type of optical thin film components.
MFrontier The developed infrared bandpass filter uses substrate materials such as monocrystalline silicon, germanium, sapphire, and zinc selenide, covering Φ 150 * 0.5 mm, Φ 100 * 0.5 mm, Φ 76 * 0.5mm, Φ Sizes such as 25 * 0.6mm can be customized as needed.
