The Gamma Scientific model RS15 Total Flux Calibration Light Source is a precision source of total radiant flux, used primarily to calibrate integrating spheres, light measuring instrumentation and as stimuli to measure detection devices. Lamps are available from 5W  75W. The RS15 source may be used as a standard of spectral radiant flux or luminous flux, traceable to the National Institute of Standards Technology (NIST).
To maintain almost constant radiant flux output, the RS15 utilizes a tungsten halogen lamp. The system can be coupled with our model RS4, ultrastable constantcurrent supply, with integral precision shunt current measurement and comparison circuits.
