product information：     Longpass filter Infrared highpass filter   Beauty Filters Color Filters   Features:   -30 degrees to +350 degrees no change in color film layer does not fall off Cutoff depth OD3-OD7 Optical indicators: Custom processing according to customer requirements One-sided T>94% Requirement Double-sided T>99% Cut off R>99% OD>3-7    Product curve：     Or customize according to customer requirements   product description：   Longpass filters have the advantages of large cutoff steepness, high transmittance, and high background light density. When the angle of incidence changes (from 0 degrees to large angles), the characteristic cutoff wavelength will shift toward the short-wave direction. This feature can be applied to fine-tune the system and get the wavelength you need. The commonly used long-wave pass filters on the beauty instrument are LP430nm, LP480nm, LP530nm, LP550nm, LP560nm, LP590nm, LP640nm, LP690. The main functions of the seven bands: 430nm, 480nm: acne, acne; 530nm: freckle; 560nm: whitening skin; 590nm: dereding; 640nm, 690nm: hair removal.   Product application：    Beauty equipment, bright light flashlight, stage lighting color film, face recognition attendance, optical instruments, fiber optic lighting, gold halogen heat insulation film, cold light display cabinet, multi-band police detection equipment.     Fluorescence analyzer, microplate reader, cable TV upgrade equipment, wireless transmission equipment, mobile barcode scanning, infrared electronic whiteboard, infrared camera, infrared touch screen, iris recognition, infrared medical equipment, infrared ink recognition, red film recognition, face recognition sensor System.
