Mirrors and lenses
for thermal imaging systems

Purpose:

The mirrors and lenses are intended for transmitting and forming optical systems in IR-imaging devices operating in static and dynamic conditions.

Applications:
  • medical diagnostic devices
  • for detection of ignition in fire-fighting systems
  • observation devices in weak illumination conditions

Polygonal mirrors for scanning units can be done with any quantity of facets as well as with any required slope of facets to the basis.


Additional features are:
  • stationary base members
  • mounting and cooling elements
  • mounting of scanning units and objective lenses
  • delivering of mirrors as the complete module combining the mirror itself and multi-functional unit applied for attaching, unloading, thermomatching and precise stationing
