A thermographic lens (also called an infrared lens or thermal imaging lens) is a device that forms an image using infrared radiation, similar to a common lens that forms an image using visible light. Instead of the 400–700 nanometre range of the visible light lens, infrared lens operate in wavelengths as long as 14,000 nm (14 µm). Their use is called thermography.

Product Description

Infrared energy is just one part of the electromagnetic spectrum, which encompasses radiation from gamma rays, x-rays, ultra violet, a thin region of visible light, infrared, terahertz waves, microwaves, and radio waves. These are all related and differentiated in the length of their wave (wavelength). All objects emit a certain amount of black body radiation as a function of their temperatures.


Generally speaking, the higher an object's temperature, the more infrared radiation is emitted as black-body radiation. A special lens can detect this radiation in a way similar to the way an ordinary lens detects visible light. It works even in total darkness because ambient light level does not matter. This makes it useful for rescue operations in smoke-filled buildings and underground, it is thermographic lens.




Thermographic cameras have slowly migrated into other fields as varied as medicine and archeology. More recently, the lowering of prices have helped fuel the adoption of infrared viewing technology. Advanced optics and sophisticated software interfaces continue to enhance the versatility of IR cameras.
