Standard Reference Board

  • Product Description

           A whiteboard is a shortened term for a standard whiteboard or reference whiteboard, which is an optical transmission standard. It is a whiteboard that has been calibrated and provides spectral reflectance data, supplied by the National Metrology Institute (National Standards Administration). Broad users rely on this data to measure the optical properties of other samples. Regardless of the instrument or method used, all measurement data must ultimately be traced back to the standard of the National Metrology Institute. Only in this way can measurements from different sources be comparable, effective, accurate, and credible.

       Optical Performance

         ●High reflectance ratio, requiring the reflectance ratio to be as high as possible, with a reflectance better than 98%.

         ●Good diffusing performance, surface without gloss, close to Lambertian diffuser. 

         ●Low spectral selectivity, i.e., good neutrality, with the same high spectral reflectance ratio for all wavelengths, using wavelength 250-2500nm.

         ●Non-transparency to avoid background and edge loss. 

         ●Good flatness and uniformity, with the entire surface flat and the same reflectance ratio at all points. 

         ●Sufficiently good optical stability.

         ●The value is traceable to PRD, with its reflectance ratio known, providing the reflectance data report from the Chinese Academy of Metrology.

        Optical Performance

           ● The reflective surface of the gray reference plate is an ideal Lambertian diffuse surface, with reflected light in any direction.

           ● The gray reference plate is primarily used for optical calibration measurements, such as light source, color, and spectral analysis.

           ● The grayscale plate has excellent optical stability and never degrades, resistant to acid, alkali, and salt corrosion.
