Ultra-Thin Optical Filter Film - Visible Light Blocking Film for Optical Research, 800-1600nm Light Penetrable(100x250x0.3mm Without Glue)

OPTICAL RANGE: filter film devised to block visible light while allowing penetration of 800-1600nm light wavelengthsFiltering films are optical films used to change the nature or color of light beams, allowing light of specific wavelengths to pass through while blocking light of other wavelengths, and only allowing light of specific bands to pass throughThe characteristics of optical films are smooth surfaces. The refractive index of the film layer can undergo a sudden change at the interface, but it is continuous within the film layer. The films used in practical applications are much more complex than the ideal onesWhen light travels from one medium to another, reflection and refraction occur at the interface. This is achieved by coating a film of a specific thickness and refractive index on the surface of optical componentsThis series of infrared filter films feature high transmittance (90%) for black light (800-1600nm), low transmittance (less than 10%) for most visible light (400-680nm), and transmittance (approximately 40%) in the transition region (680-800nm)
