Custom Coating Optical 780nm LongPass Filter Glass

Custom Coating Optical 780nm LongPass Filter Glass  Product Overview: A Custom Coating Optical 780nm LongPass Filter Glass is a precision optical component designed to transmit (pass) all wavelengths of light longer than a specific cutoff point near 780nm, while effectively blocking all shorter wavelengths. The "Custom Coating" aspect indicates that the filter's performance, particularly the sharpness of its transition edge and its blocking strength, is tailored through advanced thin-film deposition techniques to meet specific application requirements. Specification:   Key Specifications Decoded:   1. LongPass (LP) Filter:    · This defines the filter's core function. A LongPass filter has a specific cut-on wavelength. It rejects (blocks) shorter wavelengths (typically ultraviolet and visible light) and transmits (passes) longer wavelengths (typically near-infrared and infrared light). 2. Cut-On Wavelength @ 780nm:    · The 780nm wavelength is the critical point of transition. The…
