K9 Glass + Double-sided AR 29.5*27.5mm Rectangular 1mm Thickness

Introduction:
Compared with traditional colored optical glass filters, short-wave and long-pass filters have the advantages of large cut-off steepness, high transmittance and high background optical density, and are completely different from traditional optical glass methods. When the incident angle changes (from 0 degrees to large angles), the characteristic cut-off wavelength will shift to the short wavelength direction. This function can be used in system fine-tuning to get the wavelength you need.


The optical characteristics of this filter are that the light source in the 200nm band has a high transmittance of 99%. In this part of the light that passes through, the spectrum will be transparent, which can be used in various filter color products, as well as It is also essential in digital camera photography. For the detailed principle, please refer to the PL technology principle characteristics and application in the technical support.
