Photometric Integrating Sphere

Description

ntegrating sphere 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 spheres IS-*MA

Specification:
• Painting material of coating is according to CIE Pub.No.84 (1989)
• The sphere walls painting material is BaSO4 coating (PTFE material is option): ρ (λ) ≥0.96 (spectral range: 450nm~800nm) and ρ (λ) ≥0.92 (spectral range: 380nm~450nm)
• Fine diffuse with multiple reflections: 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 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 spheres is made up of several pieces. LISUN developed A-Molding Technology to produce the integrating sphere which 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 (This item is not included for integrating spheres with a diameter less than or equal to 1 meter)

Application:
The optical sphere works with a Spectroradiometer to do the photometry, colorimetry and radiometry parameters measurement.
• IS-0.3M/IS-0.5M is for LEDs, LED modules, mini LED bulbs & other small lamps. The flux testing range is 0.001 to 1,999 lm
• IS-1.0MA is for CFL or LED bulbs. The flux testing range is 0.1 to 199,990 lm
• IS-1.5MA/IS-1.75MA is for CFL, LED bulb and tube, fluorescent lamp, CCFL. The flux testing range is 0.1 to 1,999,900 lm
• IS-2.0MA is for HID lamps or high power lamps. The flux testing range is 0.1 to 1,999,900lm
