geoHEAT

Series of Lenses combining functions of Focusing the Laser Heating beam and spectroradiometric temperature measurements

With these unique achromatic lenses it is possible to focus the radiation of IR-laser beam used for heating of a sample and, simultaneously, create the image of that sample for further analyzing with using a spectrometer or other instrumerits.

Diffraction limited correction level for both optical paths: laser heating and temperature measurements.

Optimized operation spectral bands:
  • 1020 - 1100 nm for the heating channel
  • 600 - 900 or 400 - 700 nm for the channel of the spectroradiometric temperature measurements.
