Isotherm

Areas or lines of constant temperature.

Isothermal Windowing

An image processing feature which allows the user, to enhance a range of isotherm or isoradian levels.

This feature allows the user to highlight areas of similar temperature and easily find the hottest and coldest

object in an area such as an electrical distribution panel.

Joule

A measurement of thermal energy. one joule is one newton meter, 10 7 ergs, or approx. 0.737 foot-pounds.

Kelvin

The most commonly used absolute temperature scale. The scale is based on the Celsius scale degree

increment with 0 degrees K equal to absolute zero.

Kinetic Energy

The energy of motion.

Lag (Thermal Time)

The delay between the construction of a thermal gradient and the achievement of equilibrium.

Lens

An optical component constructed of transparent substance with one or two curved surfaces of different

curvature which has the ability to change the direction of beam travel. Infrared lenses are used for focusing

the detector at a distance of interest and for modifying the size and distance of the focused field of interest.
