Infrared optical materials exhibits large changes of refractive index with temperature, it leads to the focus change of Infrared (IR) thermal imaging systems. Athermalization technique is often used in design of IR thermal imaging system to eliminate its defocus over an extended temperature range, there are three main techniques: Optically Passive, Mechanically Passive and Electromechanically Active. Optically passive athermalization eliminate the defocus by combining chosen lens materials to compensate thermal focus shift, it is simple and with no moving parts, suitable for compact and light-weight design.
Hangzhou Shalom EO offers LWIR thermal camera lenses with optically passive athermalization design, in focus range of 4.3mm to 100mm and temperature range of -40℃ to +60℃, they are compact and IP67 sealing. The designed lens in list are ready for your choice and custom lens modules are also available upon your request.
