Weike Cup·OFweek 2026 Optical Industry Annual Innovation Product Award

Product Name:

A Multi-Band Optical Filter

Product Launch Year/Development Background: July 2023

Product Brief Description:

This utility model provides a multi-band optical filter for beauty devices. The key points of its technical solution include: a substrate with a first optical filter film on one side and a second optical filter film on the other side. The first optical filter film is a dual-band filter film with a filtering range of 350nm～500nm and 750nm～880nm. The second optical filter film is a triple-pass filter film acting on the 500nm～700nm band, transmitting wavelengths of 530nm～550nm, 570nm～600nm, and 635nm～650nm. This utility model can filter out harmful ultraviolet light and unnecessary wavelengths, meeting the filtering and light transmission requirements of phototherapy beauty devices, characterized by high isolation, high output power, and minimal power attenuation.

Key Innovation Points:

Innovative Breakthrough: A single filter enhances beauty device efficacy by 30%. Traditional beauty device filters have a single function, either filtering out harmful ultraviolet light or retaining only a single treatment wavelength, unable to meet multifunctional needs such as photon rejuvenation, freckle removal, and hair removal. Device manufacturers are often forced to install multiple filters, increasing optical path loss and costs while affecting overall reliability. Fair Optical's multi-band beauty device filter completely solves this industry challenge. It is the first to achieve "dual-band + triple-pass" filter film integration on a single substrate—the front side features a dual-band filter film (350-500nm + 750-880nm) for precise transmission of effective treatment light for rejuvenation and hair removal, while the back side has a 530-650nm triple-pass filter film for freckle removal and vascular treatment. The two film systems work together to simultaneously achieve harmful light blocking and precise multi-band transmission on a single filter.

Three Core Technical Breakthroughs: ① High Isolation - Out-of-band blocking depth of OD4 or higher, completely intercepting harmful ultraviolet light; ② High Output Power - The single-substrate solution reduces two optical interfaces, significantly improving the utilization of treatment light energy; ③ Minimal Power Attenuation - Optimized coating process ensures stable long-term performance, extending device lifespan. This innovation not only reduces the number of optical components and device costs but also directly enhances the end-user experience. Currently, the product is already supplied in bulk to several leading beauty device brands, helping clients establish a technological moat in the fiercely competitive market.

Reasons for Entry:

This product is a multi-band composite filter specifically designed for phototherapy beauty devices. Its core innovation lies in breaking the limitation of traditional beauty filters that only support single or dual bands, achieving an integrated solution of dual-band and triple-pass filter films on a single substrate.

In product design, the substrate features a 350-500nm and 750-880nm dual-band filter film on one side and a 530-550nm, 570-600nm, and 635-650nm triple-pass filter film on the other. This structural design ensures the product can precisely filter out harmful wavelengths such as ultraviolet light while efficiently transmitting the effective treatment light required for phototherapy beauty, effectively solving issues of rapid power attenuation and low effective light utilization in traditional solutions.

At the technological innovation level, the core challenge of this product lies in the film design for precise multi-band control across a wide spectral range and the stability of complex film structures under high-energy-density working conditions. Through repeated optimization of film layer matching schemes, the product demonstrates high isolation, high output power, and significantly reduced power attenuation during long-term use, standing out among similar products.

In terms of industrialization, the product is primarily applied in mainstream beauty devices such as photon rejuvenation and laser hair removal, meeting the market's dual demands for safety (effective filtering of harmful light) and efficacy (efficient transmission of treatment light). It has already achieved bulk application in the industry and possesses excellent market promotion value.
