Light sources

Light sources are illumination units that supply controlled light to an optical instrument, most often a microscope, either by generating the light directly or by carrying it from a separate housing to the sample through a guide. In the Questpair catalogue they appear as new, used and refurbished laboratory items, and 97 percent of the listings are used. The 253 listings span lamphouses that bolt onto a microscope stand, standalone fluorescence and fibre optic sources, and the flexible guides that deliver that light where it is needed. Prices run from EUR 15 to EUR 60.868, a spread that separates a simple light guide from a full fluorescence engine. 15 verified suppliers and distributors hold this stock across 8 countries.
