WebThermal imaging cameras and non-contact infrared (IR) thermometers are both used for non-contact temperature measurements in a wide variety of applications. Both tools work according to the same principle: they detect infrared radiation and translate it into a temperature reading. Thermal cameras however, have several advantages compared to IR … WebOptic radiations and visual pathway.

Optical radiation is part of the electromagnetic spectrum. It is subdivided into ultraviolet radiation (UV), the spectrum of light visible for man (VIS) and infrared radiation (IR). It ranges between wavelengths of 100 nm to 1 mm. Electromagnetic waves in this range obey the laws of optics – they can be focused … See more Optical radiation may be produced by artificial sources, such as UV lights, common light bulbs, and radiant heaters, but the primary source of exposure for most people is the sun. This exposure can result in negative … See more The European Union (EU) has laid down minimum harmonized requirements for the protection of workers against the risks arising from … See more WebOptical depth \tau gives a measure of how opaque a medium is to radiation passing through it. It is measured along the vertical optical path dz and, in the planetary science convention, \tau is measured downwards from the top of the atmosphere, so that \tau_{\rm top} = 0, and \tau increases downward as z decreases. The differential optical depth is defined by … opal brant wdbco
