Product Introduction Jingyi's reflectivity integrating sphere is made of imported PTFE material foam molding, covering the UV visible near-infrared spectral range, and has high reflectivity, good thermal stability, and chemical stability within this spectral range, making it less prone to yellowing and powdering. The spherical material is made of alumina, with an inner diameter of 38mm and a sample port diameter of 9.5mm. It comes with a fixed bracket for easy testing. The reflectivity integrating sphere has three openings, one of which is connected to the light source through the light inlet. The front end of the light inlet is equipped with a collimating mirror, which is incident at an angle of 8 ° to the normal. One is that the output port is perpendicular to the normal for connecting the spectrometer, and both the input and output ports are universal SMA905 fiber optic interfaces. Another one is the sample port used to prevent sample testing. Of course, Jingyi can also customize a light trap design for you, deducting the mirror reflection of the sample and only measuring the diffuse reflection of the sample mouth.
