IPL cosmetic filter is the key optical component of IPL cosmetic instrument, which can effectively prevent ultraviolet radiation. Through IPL filter glass, IPL instrument can play the role of hair removal, skin rejuvenation, freckle removal and whitening. The principle of IPL Laser Therapy Machine is that the intense pulsed light in a specific spectral range acts directly on the skin, produces photothermal and photochemistry effects, makes the collagen in the deep layer of skin tissue proliferate and elastic fibers rearrange, and restores elasticity, enhances vascular function, improves microcirculation, cracks pigments, and finally To achieve safe and effective cosmetic effect. Our glasses are mainly based on customers'light sources, customized high cut-off short wave area, high transmission long wave area of a kind of glass, from ultraviolet to near infrared band optional, projection and reflection transition band shake filter less than 20 nm, using quartz glass material, vacuum deposition coating, film can withstand flame burning firmness test. Different wavelengths have the following therapeutic effects: 430 nm, 480 nm (acne, acne), 530 nm (freckle), 560 nm (whitening and rejuvenating skin), 580 nm (blood-dispelling red silk) / 640 nm, 690 nm (hair removal). Common application equipment: IPL laser photon cosmetology instrument, hand-held cosmetology instrument, optical instrument, infrared imaging and other fields.            Shenzhen Pingzhi Optics Co., Ltd. specializes in the production of various filters, color filters: infrared filters, narrowband filters, color filters, band-pass filters, interference filters, infrared cut-off filters, attenuators (neutral density filters), long-wave pass filters, short-wave pass filters, laser cosmetology filters, face. Identification filter, iris recognition filter, 480 nm long wave pass filter, security monitoring filter, reflector, spectroscope, RGB color, IR-CUT and other professional optical filter manufacturers.
