SP680nm short pass filter

Short wavelength pass filters, as an important optical component, are widely used in digital imaging and biomedical cosmetology, fingerprint identification and other fields, and are characterized by allowing light in a certain wavelength range to pass through, while allowing light in another wavelength range to be cut off.

680nm shortwave pass filter can effectively cut off the light in the near-infrared band. It is widely used in various cold light sources, optical fiber lighting, LED lighting, gold halogen lamp insulation, and optical imaging scheme applied on the infrared cut-off filter: eliminating CCD for optical engine digital camera CMOS near infrared interference filter to ensure the normal operation of photoelectric instruments and equipment.
