Based on the use of Image Intensifier Tubes (IITs), Night Vision Devices are electro optic systems used to facilitate detection and recognition under low light conditions. Helmet, head, weapon - mounted or handheld, the products of NV family (Monoculars, Binoculars, Sights, In-line Afocals) will satisfy every operational need.
Thermal imaging devices use passive sensors that capture the infrared radiation emitted by all objects with a temperature above absolute zero (thermal radiation), providing ideal operation regardless of lighting conditions. Based on end user needs, a wide family of uncooled (Sights, In-line Afocals, Periscopes) and cooled (Binoculars) products is available.
Short-wave infrared (SWIR) light is defined in the 0.9 – 1.7μm wavelength range. Although not visible to the human eye, this light interacts with objects in a similar manner as visible wavelengths (reflective light). SWIR cameras provide high resolution imaging of objects during day / night (even moonless), but also through glass.
