This BP635 narrow bandpass filter has been renamed to suit the preferences of the majority of users. Most users, especially laser measurement and scanner, laser rangefinder users, do not have high requirements for stray light, as long as 85% of the light is filtered out, so this product is suitable for semiconductor lasers and instruments that do not participate in imaging. It can also be coated with glue or anodized into an aluminum sleeve according to special customer needs. It is also widely used in various market cashier scanners and handheld scanners, suitable for LD650, Led 635nm:, Led 640nm, Led 647nm red light receiving filters

Applications
Laser Systems: Ensures that only the laser wavelength (635 nm) is transmitted while filtering out ambient or background light.
Optical Scanning (e.g., Barcode Scanners): Enhances signal clarity by isolating the specific wavelength emitted by the laser or LED source.
Medical Imaging and Diagnostics: Isolates fluorescence or other spectral signals centered around 635 nm.
3D Scanning Systems: Optimizes light detection for structured light or scanning technologies utilizing red light sources.
