P-Shaper
geoHeat
レーザー加熱ビームの集光と分光放射温度測定の機能を組み合わせたレンズ

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

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.
