RS-10D Calibration Light Source

The RS-10D is a precision source of radiant flux, used primarily to calibrate light-measuring instrumentation and as stimuli to measure detection devices. To maintain constant output, tungsten halogen lamps are used exclusively in combination with ultra-stable constant-current supplies incorporating shunt current measurement and comparison circuits. When used with its RS-70-X accessories, the RS-10D light source can be an absolute reference for producing standard outputs in luminance units of footlamberts, lamberts, candela/m2, horizontal candlepower (candela), and spectral radiance units of microwatts/cm2 *nm *steradian or illuminance units of lumens, footcandles, lumens/m2 (lux), and spectral irradiance units of microwatts/(cm2 * nm) or Watts/(m2 * nm) at a given distance.

 

Applications

  • Calibrate spectroradiometers, radiometers and photometers
  • Calibrate detector responsivity
  • Measure reflectance and transmittance
