The integrating sphere works with a Spectrophotometer to do the photometry, colorimetry and radiometry parameters measurement, but the large size of LED and HID fixtures are difficult to be fixed in the center of integrating sphere to test. To solve this kind luminaries fixtures color temperature test, Chuangxin developed Integrating Sphere with Side Assistant Opening. There is a maximum side assistant opening to fix the lighting fixtures to test.
| Model Number | Inner Diameter | Side Opening Size |
| IS-1.5M55P | 1.5m | 500x500mm |
| IS-1.75M66P | 1.75m | 600x600mm |
| IS-2.0M77P | 2.0m | 700x700mm |
P.S. Integrating sphere with side opening of other size can be designed according to customer's request.
Specifications:
• The 4π geometry configuration and 2π geometry configuration meet IES LM-79-08 clause 9.1.2
• Painting of integrating spheres is according to CIE Pub.No.84(1989)
• Material: Pure barium soleplate (BaSO4)
• BaSO4 coating: ρ(λ)≥0.96(450nm~800nm) and ρ(λ)≥0.92(380nm~450nm)
• Fine diffuse reflection: Reflectanceρ≈0.8 and accuracy of ρ(λ)<1.5%
• Build-in lighting holder position: The vertical is for E40, E27 and so on. The horizontal is for T5/T8/T12 tubes. The side assistant opening is for lighting fixtures
• Auxiliary lamp position has been built-in. Auxiliary lamp and Auxiliary lamp device are optional
• Power cable and socket has been build-in, it is convenient to power the testing lamp
• Two photo detector ports, one optical fiber port and temperature sensor hole are built-in
• The traditional integrating sphere is assembled by several pieces, Lisun Group developed A Molding Technology to produce the integrating sphere. A molding integrating sphere will be more round and the test results will be more accurate than the traditional integrating sphere.
