Integrating sphere ITS10 - Applications

High performance precision photometer for lamp flux and / or luminous color measurement used in laboratory environments.

The OPTRONIK ITS10 integrating sphere photometer systems are designed to measure the total luminous flux, luminous color, and spectral distribution of lamps according to DIN 5032 and CIE No. 84. The systems accommodate most lamp types, including arc, fluorescent, incandescent, HID, and LED.

Each lamp measurement system features an integrating sphere, optionally calibrated lamp standard, precision power supply, photopic response detector, and display unit. The digilumen 9500 luminous flux meter used in conjunction with the sphere features the highest photometer accuracy classes L and A according to DIN 5032 and CIE No. 69 with excellent spectral matching of the high precision photopic Si-detectors to the sensitivity for brightness of the human eye.

Optional software is available for enhanced operation of the ITS10 lamp measurement system.

Optronik manufactures spheres with diameters of 50 cm and 100 cm:
