Optical indicators Transmittance band: 525nm-1100nmMinimum transmittance: T>90%Central wavelength: 515nm±3Cut-off band: 350nm-500nmCut-off depth: T<0.1% (customizable)Surface finish: National standard level 3, US military standard 40-20 (scratches/pitting) Spectrum Applications Optical beauty instruments: In photon skin rejuvenation instruments or IPL beauty instruments, the LP515 long-wave pass filter is a…
LP490nm longwave pass filter is an optical component used in optical beauty instruments. Its key feature is to allow light with a wavelength greater than 490nm to pass through, while blocking light with a wavelength less than or equal to 490nm from passing through. In…
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.…
The Spring Festival is approaching. In order to welcome and celebrate this traditional festival of the Chinese nation, combined with the actual production situation of GIAI, we hereby issue a Spring Festival holiday notice. The company has decided that from January 25 (Saturday) to February…
An optical filter is an optical element used to select the required radiation band of light, while filtering out the unnecessary wavelength range. Of course, its most essential function is to filter out unnecessary light. It plays a key role in various optical systems and…
Filters are important components in optical systems. Their performance directly affects the image quality, light signal transmission efficiency, and the overall performance of the system. Therefore, confirming the performance of filters is a key step to ensure stable and reliable operation of optical systems. We…
In the field of optics, optical filters play a vital role. They can selectively transmit or block light in a specific wavelength range and are widely used in many fields such as photography, scientific research, and optical communications. In order to better understand and select…
Optical filters are sheet-like optical elements with filtering effects. They can effectively filter, split, attenuate and reflect optics. In different application fields, the purpose of filtering is not just for simple filtering. Its “filtering” function can vary according to the actual application situation. Categorical features…
From May 14 to 16, 2024, the 16th German Optoelectronics Laser Exhibition Optatec 2024 officially opened. As a trade exhibition, the three-day Optatec 2024 will bring together optical enthusiasts from different industries and many countries. This highly specialized leading event involves optical technology, image processing,…
The Photonics West, hosted by the SPIE (Society for Photonics Engineering), has become the largest optical trade event in North America and a world-renowned exhibition in the optoelectronics industry. This exhibition attracted more than 1,300 companies and manufacturers from around the world to participate, with…
