Specification: 
• DIA: IS-0.3M (φ0.3m)、IS-0.5M (φ0.5m)、IS-1.0M (φ1.0m)、IS-1.5M (φ1.5m)、IS-2.0M (φ2.0m).  Other size can be designed according request
• Multi interface on the sphere, testing of photometers and colorimeters at the same time.
• Applications: 1. Luminous flux measurements on lamps for production and quality control, research, and development 2. Calibration of luminous flux working standards 3. Color measurements on light sources with colorimeters.
• Building position: pendant, horizontal.
• Interior sphere paint: inside painting according. to CIE Pub l. No. 84 (1989).
• Diffuse, selective reflectance.
• Reflectance р≈0.8, variation of ρ(λ)<1.5% in the visible range.
• The reflectivity curve ρ(λ) and transparency curve Ί(λ) of Spin™ coating is more smooth, longer life and more accurate than normal ones.
