TÜRKENFELD, Germany, July 1, 2014 — The ISS-17-VA integrating sphere source calibration standard from Gigahertz-Optik produces variable light intensities while maintaining a constant color temperature.
The ISS-17-VA is 170 mm in diameter with a 50-mm-diameter illumination field. The sphere is coated with Gigahertz-Optik’s highly diffused and reflective barium sulfate coating. With an integrated light source, it produces a field with homogenous light distribution within the sphere. This light source can be operated at color temperatures of 2856 and 3100 K.
The light source can be used as a calibration standard for comparison of imaging spectrometers, as well as for spectral radiance calibration of spectral meters. In these applications, halogen lamps are used to ensure optimum intensity in the blue spectral range.
