MidOpt BP635-25.5 is a light red bandpass filter that transmits 615–645 nm light and is designed for use with 615–645 nm LED laser diode sources. The part number BP635-25.5 identifies this specific filter variant and its spectral window, making it suitable for applications requiring spectral isolation in the red region. Use this filter to pass only the 615–645 nm wavelengths from your LED laser diode setup while attenuating out-of-band light.
