650nm Narrow Bandpass Filter, 40nm Bandwidth, IR Optical Coating Filter for Rangefinder
$4.20
This 650nm narrowband pass filter, with a half-bandwidth of 40nm, employs multi-layer dielectric hard-coat optical coating. The lens appears red to the naked eye, allowing only light within the target wavelength band near 650nm to pass through while deeply blocking all other wavelengths, effectively filtering out ambient stray light. The substrate is made of K9 optical glass, featuring strong adhesion of the coating layers that resist delamination under changes in temperature and humidity. It is compatible with laser ranging devices, stably enhancing the signal-to-noise ratio of photoelectric detection. The circular specifications support custom sizes as needed, making it widely used in red-light sensing and ranging optical modules.
