Editing Forward-looking infrared (section)

== Cost ==

The cost of thermal imaging equipment in general has fallen dramatically after inexpensive portable and fixed infrared detectors and systems based on [[microelectromechanical systems|microelectromechanical technology]] were designed and manufactured for commercial, industrial, and military application.<ref>Niklaus, F., Vieider, C., & Jakobsen, H.

More modern cameras no longer use this method; the simplification helps reduce cost. Uncooled technology available in many [[Enhanced_flight_vision_system | Enhanced Flight Vision System]] (EFVS or EVS) products have reduced the costs to fractions of the price of older cooled technology, with similar performance.<ref>

EVS is rapidly becoming mainstream on many fixed wing and rotary wing operators from [[Cirrus Aircraft|Cirrus]] and [[Cessna]] aircraft to large business jets.
