IPL (Intense Pulse Light) beauty instrument filters are the core optical components of IPL beauty instruments. In modern beauty technology, the main function of IPL beauty instrument filters is to block ultraviolet rays while allowing useful light in the range of 400~1100nm to pass through. This feature enables IPL instruments to act on the skin safely and effectively, achieving multiple functions such as hair removal, beauty and treatment of vascular diseases.
Principle of IPL beauty instrument
The IPL laser treatment machine directly acts on the skin tissue by emitting intense pulsed light in a specific spectral range, producing photothermal and photochemical effects. These effects can stimulate collagen proliferation and elastic fiber rearrangement in the deep layer of the skin, thereby restoring skin elasticity, enhancing vascular function, improving microcirculation, and cracking pigments to achieve the purpose of beauty treatment.
Features
Multispectral: IPL filters can select different treatment frequency bands according to different skin problems to achieve personalized treatment. Light of different wavelengths has different therapeutic effects.
For example, 430nm and 480nm are used to remove acne; 530nm is used to remove freckles, 560nm is used for whitening and tendering, 580nm is used to remove blood red streaks, and 640nm and 690nm are used for hair removal.
High energy: The intense pulsed light emitted by the IPL instrument has high energy and can quickly act on the skin tissue to produce significant therapeutic effects.
Wall-tower pulse emission: The IPL instrument adopts a wall-tower pulse emission method, which allows the light to act evenly on the skin and avoid skin damage caused by energy concentration.
Comprehensive and fast efficacy: Due to the multi-spectral and high-energy characteristics of the IPL filter, the IPL instrument can achieve a variety of cosmetic treatment effects in a short time.
Short recovery period: The recovery period after IPL treatment is relatively short, and patients can quickly return to normal life and work.
Low side effects: IPL treatment usually has low side effects and high safety.
Applications
IPL beauty instrument filters are widely used in various beauty instruments and photon machines. Long-wave pass filters can be divided into different bands (such as IPL-460, IPL-510, IPL-560, IPL-590, IPL-645, IPL-695, etc.), and these filters of different bands can meet the needs of different beauty treatments. In addition, IPL filters are also used in police multi-band detection instruments, face recognition attendance meters, optical instruments, fiber optic lighting, metal halide lamp insulation sheets, cold light source display cabinets, strong light flashlights, and stage lighting color filters.
Optical indicators
The optical indicators of IPL beauty instrument filters mainly include transmission band, minimum transmittance, center wavelength, cutoff band and cutoff depth. Taking long-wave pass filters as an example, their transmission band is usually 720nm~1100nm, and the minimum transmittance T>94%. There are multiple values for the center wavelength, such as 420nm±3@T=50%, 470nm±3@T=50%, 530nm±3@T=50%, etc. The cutoff band is determined according to specific needs, such as 200nm~410nm, 200nm~460nm, etc., and the cutoff depth T<0.1%.
Product parameters
The product parameters of IPL beauty instrument filters include material, size, thickness, aperture coating coverage, and surface finish. Common materials include B270, D263T, UVFS, and Sapphire. The circular size range is usually φ3mm~φ110mm, and the square size range is 22mm~146146mm. The product thickness is generally between 0.3~5.0mm, and the aperture coating coverage is greater than 95% of the effective area. The surface finish meets the requirements of national standard level 3 or US military standard 40-20 (scratches/pitting).
In summary, as the key optical component of IPL beauty instruments, IPL beauty instrument filters have broad application prospects in modern beauty technology. Its multi-spectral, high-energy, wall-to-wall pulse emission, fast comprehensive efficacy, short recovery period and low side effects make IPL instruments the new favorite in the beauty industry. With the continuous advancement of science and technology and the continuous development of beauty technology, the application of IPL beauty instrument filters will be more extensive and in-depth.
