3 Terms and units of measurement
3.1 Infrared radiation
This specification refers to light radiation with a wavelength of (2.5 ~ 300) μm, and its corresponding wavenumber range is (4000 ~ 33) cm-1.
3.2 wavenumber
The reciprocal of the wavelength (symbol λ) is the wave number (symbol υ), and the unit of measurement is cm-1.
3.3 Infrared wavelength standard filter
The wavelength (or wave number) corresponding to the absorption peak or transmission peak in the infrared band is used to transfer the standard of the wavelength (or wave number) magnitude
Quasi-filter, its main measurement technical index is wavelength or wave number, measurement unit is μm or cm-1.
3.4 Infrared transmission standard filter
The standard filter used to transmit the spectral transmittance in the infrared band, whose main parameter is the spectral transmittance
τ), the dimension is 1.
3.5 Infrared Stray Radiation Standard Filter infraredstraylightstandardfilter
The standard filter used to evaluate the relative amount of stray radiation in the infrared cut-off region of the instrument
Spectral transmittance indicates that the dimension is 1.For the stray radiation in this specification, please refer to 4.83 heterochromatic spurious in JJF 1032-2005
Definition of radiation.
4 Overview
Infrared standard filter is a measurement standard used to verify or calibrate the wavelength, transmittance and stray radiation of infrared spectrometer
Quasi-apparatus.
Commonly used infrared standard filters are divided into infrared wavelength standard filters (polystyrene film filters), infrared transmission
Than standard filters (neutral transmittance standard filters, rotating sector disks), infrared stray radiation standard filters (melt
