Laser Beauty Filter
We are an optical bandpass filter design corporation in China. Our Laser Beauty Filter is mainly to filter out the ultraviolet rays that are harmful to the skin by using a specific long wave pass filter and selecting a specific treatment spectral band to achieve the effect of beauty treatment for different skin problems.
What are the applications of filters in the beauty instrument industry?
In this era of looking at the face, more and more people are willing to invest and pay for beauty, ranging from cosmetic surgery to freckle removal, whitening, hair removal, etc. Therefore, more and more beauty instruments are swarming, including handheld beauty instruments, laser beauty instruments, etc. now the safest routine is laser beauty instruments, and the role and performance of each laser beauty instrument are also different, This is because different beauty instruments use different optical lenses - filters, so the effect is also different.
The filter of beauty instruments is mainly to filter out the ultraviolet rays that are harmful to the skin by using a specific long wave pass filter and selecting a specific treatment spectral band to achieve the effect of beauty treatment for different skin problems. Gengxu photoelectric's long wave pass filter has two kinds of absorption and reflection and has the advantages of high transmittance, good cut-off rate, and good stability.
With the increasingly hot beauty market, the demand for beauty instruments is also increasing.
The principle of the filter of beauty instruments is that the strong pulse xenon lamp emits a wide spectrum of light. By using a specific long wave pass filter to filter out ultraviolet light and select the standard spectral band for the treatment range, it acts on human skin tissue to achieve the effect of beauty treatment. The difficulties in the film system design and preparation process of related filters lie in the requirements of high band transmittance, wide cut-off band, and high steepness of such filters.
The main wave bands of the filter of the beauty instrument are 430nm, 480nm, 530nm, 560nm, 580nm, 640nm, 690nm, etc. it is used as a hair removal instrument, freckle remover, photon rejuvenation instrument, etc.
Lp430nm: acne removal, hemorrhoids removal
Lp580nm: dispel red blood filament
Lp480nm: acne and hemorrhoids
Lp640nm: hair removal
Lp530nm: freckle removal
Lp690nm: hair removal
Lp560nm: whitening and rejuvenating
What are the materials of filter lenses?
The filter is the main optical lens, and the main material selection is determined by its transmissivity and refractive index of various colors of light. Therefore, the optical lens is the transmission material, which mainly includes three types: optical glass, optical crystal, and optical plastic.
Optical glass
Optical glass is the most commonly used optical material. Its manufacturing technology is mature and its variety is complete. Generally, optical glass can transmit all kinds of colored light with a wavelength of 0.35-2.5nm. Light beyond this band range will be strongly absorbed by the optical glass.
Optical crystal
The transmission band range of optical crystal is a little wider than that of optical glass, and its application will be increasingly extensive.
Optical plastic
Optical plastics mainly refer to organic materials that can be used to replace the optical glass. They are mainly called infrared transparent acrylic PMMA, PC board, etc. they have the advantages of low price, low density, lightweight, easy molding, low cost, high production efficiency, and not easy to break. They have gradually replaced optical glass materials in the developing optical instrument industry.
