The synchrotron radiation spectra of toroidal grating monochromators (TGM) often contaminated by significant amounts of higher orders. Quantitative estimation of order contamination is essential in order to perform quantitative spectroscopy measurements. At Indus-1 reflectivity beamline higher order contaminations from TGM monochromator are experimentally determined using a reflection grating analyzer. It is found that the order contamination in wavelength range of 50-200 A is less than 15%. Use of edge filters reduces the order contamination level below 5% in this wavelength range.
