Abstract

For the measurement of a spectrum with an optical multichannel detector (OMCD), the relation <i>N</i> = <i>N</i>(λ) or λ =λ(<i>N</i>) between the channel number <i>N</i> and the wavelength λ must be known. For an ideal OMCD, <i>N</i>(λ) and λ(<i>N</i>) are completely defined by the physical parameters of the monochromator and the channel spacing of the OMCD. Series expansions <i>N</i> = <i>N</i>₀ + Σ_<i>k</i>A_<i>k</i>(λ – λ₀)^<i>k</i> and λ = λ₀ + Σ₀<i>B</i>_<i>k</i>(<i>N</i> – <i>N</i>₀)^<i>k</i> are given for single-grating monochromators (<i><i>k</i></i> = 1, 2, 3) and double-grating monochromators (<i>k</i> = 1, 2). The validity of the series expansions has been checked experimentally and numerically for a double monochromator.
