Absolute magnitude

In astronomy, absolute magnitude is a measure of the luminosity of a celestial object on an inverse logarithmic astronomical magnitude scale.

See K band (infrared) and Absolute magnitude

Infrared (IR; sometimes called infrared light) is electromagnetic radiation (EMR) with wavelengths longer than that of visible light but shorter than microwaves. K band (infrared) and infrared are electromagnetic spectrum.

See K band (infrared) and Infrared

Infrared astronomy

Infrared astronomy is a sub-discipline of astronomy which specializes in the observation and analysis of astronomical objects using infrared (IR) radiation. K band (infrared) and infrared astronomy are infrared imaging.

See K band (infrared) and Infrared astronomy

Infrared detector

An infrared detector is a detector that reacts to infrared (IR) radiation. K band (infrared) and infrared detector are infrared imaging.

See K band (infrared) and Infrared detector

Infrared window

The infrared atmospheric window refers to a region of the infrared spectrum where there is relatively little absorption of terrestrial thermal radiation by atmospheric gases. K band (infrared) and infrared window are electromagnetic spectrum.

Mercury cadmium telluride

Hg1−xCdxTe or mercury cadmium telluride (also cadmium mercury telluride, MCT, MerCad Telluride, MerCadTel, MerCaT or CMT) is a chemical compound of cadmium telluride (CdTe) and mercury telluride (HgTe) with a tunable bandgap spanning the shortwave infrared to the very long wave infrared regions.

Photometric system

In astronomy, a photometric system is a set of well-defined passbands (or optical filters), with a known sensitivity to incident radiation.
