Molecules of carbon dioxide (CO 2) can absorb energy from infrared (IR) radiation. This animation shows a molecule of CO 2 absorbing an incoming infrared photon (yellow arrows). The energy from the photon causes the CO 2 molecule to vibrate. Some time later, the molecule gives up this extra energy by emitting another infrared photon.

Due to the increase of anthropogenic carbon dioxide and its highly politicized global effects, there has been much research concerning the absorptivity of CO 2 and its thermal effects. CO 2 contributes to the greenhouse effect by absorbing energy in the infrared (IR) wavelengths, thus trapping heat within the boundaries of the earth’s atmosphere.

A common application for CCD cameras is to block off the nearIR (700 to 1000nm). Since most light sources emit light in the nearIR, a filter is required to pass only the visible spectrum (400 to 700nm). The type of filter that passes the visible and blocks the nearIR is a Shortpass (opposite of Longpass) filter.

Feb 16, 2020· The hypothesis of global warming from man made CO2 depends on a muchrepeated narrative about CO2 trapping infrared (IR) photons leaving the earth. Although a beguilingly simple idea, a host of assumptions underlie it. One of these is that the radiative photonic absorption emission interactions of the trace gas CO2 dominate heat movement in…

The intensity of the IR light decreases significantly above 4 mm with a cutoff wavelength located at 5 mm. A Visible/IR lamp is a very costeffective component for an NDIR sensor, but it has a limited IR range. For carbon dioxide (CO 2) and hydrocarbon (HC) detection, it is an ideal technique. The most desirable NDIR lamp characteristics are:
