Integrating Sphere with Side Assistant Opening

IES LM-79 Clause 9.1.2 requests the 4π geometry and 2π geometry configuration integrating sphere for the LED testing. LISUN developed the photometric integrating sphere with side assistant opening using a-molding technology to meet the requirements. The IS-*MA**C/IS-*MA**P integrating sphere has all of the specification of IS-*MA.

The traditional integrating sphere is assembled by several pieces. LISUN developed A-Molding Technology to produce the sphere. A-Molding integrating sphere will be more round and the test results will be more accurate than the traditional integrating sphere.

A-Molding Integrating Sphere VS The Traditional Integrating Sphere

Specification:
• Painting material of integrating spheres is according to CIE Pub.No.84 (1989) and IES-LM-79 Standard.
• The inernal 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: 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, power terminal are built-in. It is convenient to power on the lamp under test
• Two photo detector ports, one optical fiber port and one temperature sensor port are built-in
• Build-in cross laser can help to install the standard lamp and the lamp under test in the center of the integrating sphere (This item is not included for integrating spheres with a diameter less than or equal to 1 meter)

P.S. Other size integrating spheres can be designed according to customer‘s requirement.
