Broadband Spectroradiometer with Integrating Sphere

specbos 1311

specbos 1311 is a spectral measuring system for characterization of light sources with regard to their 4 π radiant flux and related colorimetric/ photometric data (download datasheet).  


It consists of

  • the basic model specbos 1211
    (which can also be used separately)
  • a hinged integrating sphere
    with a diameter of 500 mm
  • an internal sample holder (which can be modified according to individual requests)
  • an auxiliary lamp with shutter
    (to compensate self absorption effects)

The sphere is equipped with an additional outside sample port to allow 2 π measurements too.
