Integrated Sphere
At CTL, all photometry parameters like Total Luminous Flux, Luminous Intensity Distribution, Luminous Efficacy, Color Characteristics can be tested in Integrated Sphere for performance testing of Lamp/Luminaries. This test is covered in LM 79, IS 16106, IS 16102 (Part 2), IS 15111(Part 2), IS 2418 and various other Indian as well as International Standards. |  |  | Integrating Sphere is used for a variety of optical, photometric or radiometric measurements. It can be used to measure the diffuse reflectance of surfaces, providing an average over all angles of illumination and observation. |
