FIELD: optics.
SUBSTANCE: invention relates to microscopy. Microscope lighting system comprises at least one light source to generate two collimated light beams to object surface, where two collimated light beams at least partially overlap, and retractable beam splitter in microscope line of sight. Beam splitter provides reflection of part of two collimated light beams to object surface so, that they partially overlap on the surface of object, and is retracted beyond microscope line of sight, when lighting system is not used. Retractable beam splitter enables to use non-coaxial illumination without reducing illumination level, which reaches operator when beam splitter is taken away from operator line of sight.
EFFECT: as a result one system can be used for producing lighting of different types.
