Many optical lenses have high reflectivity requirements, but the spectrophotometer is not accurate for high reflectivity samples. CRD high reflectivity measuring instrument can be used to perform high-precision reflectivity measurement at 1030nm. CRD uses the cavity ring-down method to measure reflectivity. When a pulsed laser is incident into the optical cavity along the optical axis, diffraction and scattering losses are ignored. The monochromatic pulse light oscillates back and forth between the two cavity mirrors, and part of the light is transmitted after each cycle. The detector receives the light pulse signal and obtains its attenuation in the form of a single exponential. Through the accumulation of process technology, the high-reflectivity film is measured by CRD, and the reflectivity is>0.999670.
