              Diffuse reflection standard reference plate
              Date:2018-05-30 16:28
              •  Product overview

                 The standard reference plate for diffuse reflection is made of international standard material PTFE by special technology and has good diffuse reflection characteristics. By adding only a small amount of black material in the developed reference body, a standard reference plate with a certain gray scale can be obtained, and the optical characteristics are similar to those of a high reflective reference plate. By detecting the spatial reflection distribution characteristics of the diffuse reflection reference body / target, the quantized parameters of the product direction - hemispherical reflection ratio DHR (directional hemisphere reflectance) and the bidirectional reflectance factor BRF (bidirectional reflectance factor) are provided for the end users. The features of the product are as follows

                 The whiteboard has a high reflectivity ;

                 With better spectral flatness ;

                 With better spatial distribution characteristics ;

                 Traceability to the national standard of China National Metrology Institute .

                 The product is specially designed for aluminum alloy box, suitable for field spectrum measurement and transportation protection.

                Physical picture

                     The diffuse reflectance standard reference plate (reflectivity 99%) of different specifications is shown in Figure 1, and the standard reference plate of 500mm * 500mm specs is as shown in Figure 2.
