A surgical microscope (1) for ophthalmology includes a tube unit (5) which
permits viewing an area (7) of surgery, especially a forward section of
the eye, through a microscope main objective (2). The surgical microscope
(1) includes an illuminating system (10) which makes available the
illuminating light to illuminate the surgical area (7), especially the
forward section of the eye. To provide daylight-like illuminating light,
the illuminating system includes a xenon illuminating light source (11)
or a metal halide illuminating light source. At least one interference
filter (22, 23) is provided in the illuminating beam path (16). The
cutoff frequency of the interference filter lies such that illuminating
light in the ultraviolet range is filtered out and illuminating light in
the visible wavelength range is attenuated, if at all, to an
insignificant extent in order to reduce the phototoxicity of the
illuminating light for the human eye.
