Product features:
Compared with the traditional colored optical glass filter, the long wave pass filter produced by our company has the advantages of large cut-off gradient, high transmittance and large background light density, and is completely different from the traditional optical glass method. When the incidence angle changes (turning from 0 ° to large angle), the characteristic cut-off wavelength will move to the short wave direction. This function can be applied in system fine-tuning and can obtain the wavelength you need.
The optical characteristics of this filter lie in the high transmittance of the light source 560-1200nm in the 350-490nm wavelength range. In this part of the transmitted light, the spectrum will be yellow, which can be applied to various filter color products. It is also essential in IPL beauty. The detailed principles can be supported by production technology, including the characteristics and applications of PL technology. The IPL beauty filter is a key optical component of the IPL beauty instrument, which can effectively block ultraviolet rays. Through IPL filter slides, IPL instruments can achieve hair removal, skin rejuvenation, freckle removal, and whitening effects. The principle of IPL laser therapy machine is to use strong pulse light within a specific spectral range to directly act on the skin, generating photothermal and photochemical effects, causing collagen proliferation and rearrangement of elastic fibers in the deep skin tissue of the body, restoring elasticity, enhancing vascular function, improving microcirculation, cracking pigments, and ultimately achieving safe and effective cosmetic effects. Our glass slides are mainly customized based on the customer's light source, with a high cutoff short wave zone and a high transmittance long wave zone. They can be selected from the ultraviolet to near-infrared bands, and the projection and reflection transition band is less than 20nm. We use quartz glass material, vacuum deposition coating, and the film layer can withstand flame burning for firmness experiments. Different wavelengths have the following therapeutic effects: 430nm, 480nm (acne removal, acne removal), 530nm (freckle removal), 560nm (whitening and rejuvenation), 580nm (blood and red silk removal)/640nm, 690nm (hair removal).
