Mangal instrumentation provides photometric integrating spheres manufactured by sensing of china. These photometric integrating spheres are used to determine luminous flux, radiant flux, uv radiant power and spectral power distribution for cfls, leds, incandescent lamps, hid lamps, etc. Photometric integrating spheres are available in different internal diameters. They have highly diffuse and reflective interior coating, direct-tospectrometer for fibre bundle connection, video monitor window, pneumatic door, high precision thermostat and cross laser positioning. All types of photometric, calorimetric, goniophotometric, spectroradiometry as well as electricity are available and widely used in inspection, quality control, and metrology of light sources, light fitting, luminous material and display devices, etc.
