Sensors as well as varios systems on their base are widly used and discover new and new areas for applciations on almost all aspects of human activity. Optical IR-sensors and detectors belong to a special niche since are allowed to control and manage the processes which take place at room and much low temperatures. Majority of the devices here are remote-acting and non-contact.
Application of Wien's law to human body emission results in a peak wavelength of

For this reason, thermal imaging devices for human subjects are most sensitive in the 7‑14um range.

For monitoring and temperature measurements of higher heated environments the wavelength range 3-5um is used.
Practically all organic and inorganic compounds have the unique feature that they more or less good absorb at the diapason of 2‑15um. This cause the wide products line of IR-sensors and IR-detectors.
Tydex introduces various passive optics for the discussed topic.
Hereunder are some examples of the optical elements demonstrating the range of our products. Additional information is available in the following chapter - Frontal optics for ultimate applications.
