The IS-*M is the tradiontal integrating spheres, LISUN already stop producing it but instead with A molding technology integrating sphere IS-*MA

A Molding Integrating Sphere VS The Traditional Integrating Sphere

Specifications:
• Painting material of integrating spheres 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 integrating sphere is made up of several pieces. LISUN developed A Molding Technology to produce the integrating sphere. A molding integrating sphere is more round and the test result is with more accuracy.

Applications:
The integrating sphere works with a Spectroradiometer to do the photometry, colorimetry and radiometry parameters measurement.
