Luminous flux measurement integrating sphere IS-*M

Integrating sphere is a hollow sphere with high reflectance surface, it is widely applied in testing lumen, chromaticity coordinates, CCT, dominant wavelength and peak wavelength etc for light source or luminaries. The IS-*M is the tradiontal integrating sphere, LISUN already stop producing it but instead with A molding technology integrating sphere IS-*MA • Painting material of sphere integration system is according to CIE Pub.No.84 (1989) • The painting material is BaSO4 coating: ρ (λ) ≥0.96 (450nm~800nm) and ρ (λ) ≥0.92 (380nm~450nm) • Fine diffuse reflection: Reflectance ρ≈0.8 and accuracy of ρ (λ) <1.5% • Build-in all functional lamp testing jigs: for E40/E27, T5/T8/T12 tubes and the testing holder base for LED and other luminaires. All samples under test can be installed both up and down directions in the sphere. • Power cable, power terminal and auxiliary lamp position are built-in (Auxiliary lamp is optional) • Power cable and socket has been build-in. It is convenient to power on the lamp under test • Two photo detector ports, one optical fiber port and temperature sensor hole are built-in • The traditional integrated sphere is made up of several pieces. LISUN developed A Molding Technology to produce the integrated spheres. A molding integrating sphere is more round and the test result is with more accuracy • Build-in cross laser can help to install the standard lamp and the lamp under test in the center of the optical sphere
