ABSTRACT:
A brightfield/darkfield microscope illuminator has two axicon mirrors and a third plane mirror for use with two light beams from different sources. An open shutter positioned in the path of one beam provides brightfield illumination. An open shutter positioned in the path of the other beam provides darkfield illumination. This illuminator easily switches between operation in the darkfield and brightfield modes, uses substantially all the light in one beam for darkfield illumination and easily balances the illumination between the two light sources.
