Night Vision and Thermal Systems

Thermal imaging scopes and viewers

The increase in radiation emission is directly proportional to the increase in temperature of an object, hence, one what one can see through thermal imaging cameras are varying levels of temperature of images. Warm objects tend to become highlighted from dark colored objects which are supposed to be cool ones such as the environment. There is a sort of luminance or glow against a cool and dark background.

This technology has been largely utilized by firefighters to locate the central part of the fire, to search for missing persons in a pile of large debris, or to see through thick smoke. This tool was also used during the 2009 pandemic phenomenon, due to the infamous outbreak of the swine flu virus.

The military force made a good use of this technology in their operations, especially covert ones. It was also used to see through thick smoke during war encounters for a better and advantageous visibility of their environment. They tend to base their tactical plans according to the read that they would be getting from the thermal imaging camera. Through this, soldiers assigned behind their weapon with thermal rifle scope can see a real time movement of their targets. This thermal weapon sight, or thermal rifle scope as it is commonly called, is become an essential accessory of today modern warfare armament and most and more guns like assault and sniper rifles, light and sub-machine guns which are already issued to troops has this high tech add-on installed on them as it allows them to obtain a good enough visual of their target through sight hindrances such as the ones already mentioned above.

These thermal imaging devices are made available to personnel and agencies who are into covert operations, tactical entries, surveillance and search and rescue. The popular models already released in the market are the following:

Thermal Acquisition Monocular (TAM-14), a lightweight, quick-rail and rugged designed, with a head, helmet or weapon mounting options and extended battery life of up to 4 hours of continuous use.

Thermal Imaging Weapon Sight (TWS-37), which has a digital zoom control of up to 2x to 4x , with a Black Hot/White hot polarity switch and a GSCI Propietary 3-stage Contrast Enhancement Feature for better imaging. This was made from aircraft aluminum body which covers its strength and durability, and at the same time, being fully-sealed for waterproofing.

Thermal Imaging Monocular (TIM-14) is a higher version of the TAM-14. Additions to its features are the multi-use system design, shutter less and soundless internal movements, and even a lesser power consumption of up to 5 hours of continuous use.

Thermal Imaging Goggle (TIG-7) is a binocular-type version of the TIM-14, though lighter in weight and can stay longer with continuous use of up to 10 hours.

Thermal Weapon Sight (TWS-37) High Resolution 640×480 is an upgrade of the older TWS-37. It has a higher resolution than its predecessor as it carries an F.P.A. Sensor Format of 640×480, in comparison to the 320×240 resolution of the former. It also has longer range coverage.

Thermal Imaging Binoculars (TIB-5E) is another binocular-type with a longer focal range and digital zoom than the TIG-7. It has a lesser continuous battery operation of up to 7 hours though.

“Clip On” Thermal Imaging Scope (CTS-22) is designed for daytime rifle. It last up to 3 hours of continuous use.

Head Mounted Display (HMD-640) is a 3.3”x2.3”x2” display that can be connected to any aforementioned thermal imaging devices that has analog video output.

There is a low supply of thermal devices released, hence, the price range benchmarks at around $6,000 each. Any upgrade on the specifications requires more effort and funding in several aspects than the normal camera since it is identified as one new technology.
