FIELD: physics.
SUBSTANCE: apparatus for measuring surface temperature in the region exposed to laser radiation has a galvano scanner with a F-teta lens and a two-channel optical pyrometer with a lens. The apparatus additionally includes a gradient mirror with a central elliptical region with 100% transmission of laser radiation and with a broadband reflecting coating on the periphery of the mirror, lying at an angle of 45° to the optical axis and optically connected to the laser and the optical pyrometer with a lens, wherein the pyrometer detects thermal radiation of the surface in several narrow spectral intervals near the laser radiation line and in the reflection spectral band of the mirrors of the galvano scanner.
EFFECT: design of an apparatus for measuring surface temperature in the region exposed to laser radiation when scanning the surface with a galvano scanner with a F-teta lens.
