At Eurosatory 2018, Ophir introduced another infrared thermal imaging lens to the range, the LightIR 15-75mm f/1.2, for uncooled 10–12-μm-pixel-size long–wave infrared (LWIR) detectors. [6] In 2019, Ophir expanded its family of cooled MWIR long range lenses, adding 900mm and 1350mm FLs, for use in aviation and observation systems. [7]

Fine Guidance Sensor and Near Infrared Imager and Slitless Spectrograph (FGS-NIRISS) is an instrument on the James Webb Space Telescope (JWST) that combines a Fine Guidance Sensor and a science instrument, a near-infrared imager and a ...
Near-infrared spectroscopy is used in astronomy for studying the atmospheres of cool stars where molecules can form. The vibrational and rotational signatures of molecules such as titanium oxide, cyanide, and carbon monoxide can be seen in this wavelength range and can give a clue towards the star's spectral type .
The device enhances ambient visible light and converts near-infrared light into visible light which can then be seen by humans; this is known as I 2 (image intensification). By comparison, viewing of infrared thermal radiation is referred to as thermal imaging and operates in a different section of the infrared spectrum.
Diffuse optical imaging (DOI) is a method of imaging using near-infrared spectroscopy (NIRS) [1] or fluorescence-based methods. [2] When used to create 3D volumetric models of the imaged material DOI is referred to as diffuse optical tomography , whereas 2D imaging methods are classified as diffuse optical imaging .
