Specification:
• DIA: φ0.3m、φ0.5m、φ1.0m、φ1.5m、φ2.0m.
• 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 Sphin™ coating is more smooth, longer life and more accurate than normal ones.
