TOP 200 Telescopic optical probe

Telescopic optical probe for radiance and luminance measurements

The TOP 200 telescopic optical probe is typically used for the testing of displays and panel graphics. It has been completely redesigned and is now based on Pritchard style optics with an integrated alignment camera. In comparison to the previous model (TOP 100), all functions are now controlled via software, so that manual operation is no longer required except for focus adjustment.

Light is guided from the TOP 200 to the spectrometer via a multimode fiber. A patented mode mixer from Instrument Systems ensures consistent transmission through the fiber. This feature guarantees reproducible measurement results, even when the fiber is physically disturbed somewhere along its length.

Use of a Pritchard style optic means that the viewing area around the spot can be observed and monitored during the measurement. The image generated by the alignment camera is automatically imported by the SpecWin Pro software and saved together with the measurement results.

Features:

  • Pritchard optics with an aperture mirror inclined at only 15° delivers perfectly round and sharp image spots (products from other manufacturers can exhibit ellipticity and blur)
  • flexible connection via optical fibers incorporating a patented mode mixer ensures reproducible results and very low polarization sensitivity
  • 6 different measurement spot sizes selectable via software
  • internal alignment camera with a wide field of view
  • smallest measurement spot 80 µm
  • optional illumination of the test object
