Optical thermometer
WebJan 1, 2024 · LIR based optical thermometers are usually constructed using thermally coupled energy levels in a single-emission-center phosphor. Energy separation of thermally coupled levels should not exceed 2000 cm −1, which imposes a fundamental limitation of relative thermal sensitivity and can cause a problem with signal discriminability [ 24, 25 ]. WebBroadband Radiation temperature sensors Broadband non-contact thermometers typically are the simplest devices, cost the least, and can have a response from 0.3 microns wavelength to an upper limit of 2.5 to 20 microns. The low and high cut-offs of the broadband thermometer are a function of the specific optical system being used.
