Noncontact infrared temperature sensors absorb ambient infrared (IR) radiation given off by a heated surface. They are used in applications where direct temperature measurement is not possible

Infrared heaters use a reflective shield to direct radiant heat onto a heated surface

Thermal imagers detect heat patterns in the infrared wavelength (1 micron to 100 micron) spectrum

Infrared (IR) spectrometers measure the wavelength and intensity of the absorption of infrared light by a sample

Temperature sensors are measurement devices that infer temperature by sensing some physical characteristic (i.e. resistance, emf or thermal radiation).

Temperature instruments use contact or noncontact methods to measure temperature. Products include dial, digital, industrial and laboratory thermometers; temperature probes, indicators, and sensors; RTD elements and transmitters; and thermistors, thermocouples, thermopiles, and thermal switches. 

Spectrometers are analytical instruments which disperse an emission (such as particles or radiation) according to some property of the emission (such as mass or energy) in order to measure the amount of the dispersion. This product area includes visible, infrared (IR), ultraviolet (UV), atomic absorption (AA), optical emission (OE), Raman, X-ray fluorescence (XRF) and mass spectrometers. Specific search forms are also available

Camera filters provide a range of optical filtering effects in scientific, research, and industrial applications.

Infrared Sources are optoelectronic devices that emit infrared light

Light-emitting diodes (LED) are PN junction devices that give off light radiation when biased in the forward direction. LEDs are used in a wide variety of indication applications.

Heat lamps are also known as infrared emitters, infrared bulbs, infrared tubes, or infrared lamps. Heat lamps differ from illuminating lamps in their low filament temperature, resulting in much less light and more infrared radiation

Photoelectric sensors use emitters and receivers to detect the presence, absence, or distance of target objects.

Moisture meters are used to measure the moisture content in bulk solids, liquids and gases.

Optical triangulation position sensors use reflected waves to pinpoint position and displacement.

Lamps are light sources that emit incoherent light for illumination. There are many different types of products. Examples include fluorescent lamps, halogen lamps, heat lamps, incandescent lamps, LED lamps, projection lamps, spectral lamps, and stage lamps. Specialized and proprietary lamps are also available.
