As a luminance source, it provides standard color temperature, spectrum, Illuminance/Irradiance values, tracing to NIM.

  1) The halogen lamp as light source, it diffuses in the integrating sphere, the uniform luminance source acquires at light outlet.

  2) The size of light outlet can be adjusted from 30mm~60mm when different sizes of integrating spheres are chosen.

  3) For different distribution design of light source, luminance uniformity reaches 90%~99%.
