Model :LS-Short Pass Filter
Introduction: It is a type of filter that allows short-wave light to pass through while blocking long-wave light. The short-wave pass filter produced by our company has the advantages of a small cut-off slope, high transmittance, and high cut-off background light. Moreover, a completely different point from the traditional optical glass method is that when the incident Angle changes (from 0 degrees to a large Angle), the characteristic cut-off wavelength will shift towards the short-wave direction Move. This function can be applied to system fine-tuning and can obtain the wavelength you need.
