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
Example of imaging layout, magnification -12.5
