Characterization of spectrometers and their related sources

摘要

The invention relates to an optical spectrometer (2), which comprises:-A first detector (14) configured to output a measurement signal, and a first optical filter (16) as an input to the first detector, which has a transmission that preferably varies monotonously with wavelength;-A second detector (18) is configured to provide a reference signal, a second optical filter (20) serves as an input to the second detector, and has a transmission constant with a wavelength;-A spectrometric device (8) configured as:The measurement data is determined according to the measurement signal and the reference data is determined according to the reference signal;Calculation of standardized data based on measured data and reference data; andThe wavelength of the incident radiation is determined based on the standardized data and the transmission of the first optical filter.Abstract figure: Figure 1
