Product Introduction The cosine corrector JY-CC-3 is an optical component used for spectral radiation sampling, which is used to collect radiation within a 180° solid angle, thereby eliminating optical coupling problems caused by the geometric structure limitations of light collection sampling in other sampling devices. Connection with fiber optic and spectrometer for relative and absolute spectral intensity measurement, emission spectrum measurement, and analysis of LED and laser light sources. The effective diameter of JY-CC3 cosine corrector is 3.5mm, made of imported PTFE material, and can be used in the wavelength range of 200-2500nm. The cosine corrector can be connected to any SMA connector fiber optic cable.
