Be regarded as the core lens for the new generation of temperature adaptive infrared optical system, HWS chalcogenide infrared glass has good transmission at mid-infrared spectrum and excellent athermal performance. It can be widely used in military (night vision sighting, fighter night vision cruise, etc.) and civil (automobile night vision, security monitoring, etc.) infrared optical systems.
The supply forms include blanks and polished parts.
