Broadband Spectroradiometer  

specbos 1211focus


The standard version of specbos 1211 can measure in Luminance mode only with diameters of 4 mm and more. Therefore three focusing optics were developed to allow the measurement of spots with 3 mm, 1 mm and 0.5 mm diameter. These spots are marked by a laser circle. The 0.5 mm add on is fitted out with a magnifying glass to simplify the precise adjustment.

Measuring objects:

  • Alphanumerical and numerical displays
  • Fluorescent tubes with small diameter
  • Backilluminated signs
  • Other small light sources
All focusing optics can easily be attached to the basic instrument by screwing. The type is automatically detected and the appropriate calibration data will be applied.
