IR optics is widely used when the tasks like the following are arisen:
1) Si protection window for a night-sight operating at 3-5um range Generally used as a front window transmitting over the working range to protect an optical assembling of IR night vision system. Detection range is 10km. In combination with a window for a visible channel (for a daylight inspection - see below #2) such night-sights are placed at some military-oriented vehicles.
Specification:
2) Radiation-resistant glass К108 window for a night-sight Application - see above #1. This window is placed near the above-mentioned Si window and operates in the day-time. Combination of AR coating outside and indium tin oxide (ITO) coating from inside allows to minimize residual reflection and prevent ice accretion, snow ticking аnd to conduce of water/hoar/ice removal. As a result a window effectively works at three working wavelength ranges.
3) Ge meniscus lens of thermal vision system for target-seeking and flight orientation Application - on-board equipment. Working wavelengths range - 3-5um. Working angles range - 0-57 degrees.
4) Ge protection window for a night-sight operation at 8-12um range Application - periscopic night-sight for the armoured vehicles. Detection range (the target like a tank) is 3km.
5) Ge protection meniscus lens for infrared imaging camera operating at 7-14um Application - passive surveillance system of long-distance targets as well as large area monitoring in real time regime. The feature of the system is automatic detection and target's tracking. Vehicle detection range is 7km. Human detection range is 3km.
6) ZnSe protection meniscus lens for a land-based thermal vision system Application - monitoring, seeking and tracking of various flying objects.
7) Sapphire window for infrared imaging camera operating at 3-5um range Application - the most demanding and severe working conditions when an application dictates the exaggerated requirements to durability of the material, its chemical stability, non-toxicity and so on. We have been suppling similar windows for: - the systems to measure temperature profile and speeds of the liquid's flow; - protection of the objectives during high pressure experiments as well as at dynamic impacts; - observation of the processes into the wind-tunnels.
