SpecificationsPainting 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) Etc.
According to IES LM-79 Clause 9.1.2, it request the 4π geometry configuration and 2π geometry Integrating Sphere for the LED Testing. Lisun Group developed the integrating sphere with side assistant Opening in A Molding Technology to meet the requirements. The traditional integrating sphere is assembled by several pieces. Lisun Group developed A Molding Technology to produce the sphere. A Molding Integrating Sphere will be more round and the test results will be more accuracy than the traditional integrating sphere.
