550nm long wave pass filter

The long wave pass filter has the advantages of large cut-off steepness, high transmittance and high background light density. It is completely different from the traditional optical glass method. When the incident angle changes (rotating from 0 ° to a large angle), the characteristic cut-off wavelength will move to the short wave direction. This function can be applied to system fine-tuning and get the wavelength you need.


The optical characteristic of 550nm long wave pass filter is that the light source in the cut-off 350-490nm band has a high transmittance of 560-1200nm. In this part of light, the spectrum will be yellow, which can be applied to products with various filter colors and is also essential in IPL Beauty
