Abstract
Systems and methods are provided for illuminating a surface to be observed microscopically using a retractable beamsplitter. The retractable beamsplitter allows the use of coaxial illumination when the beamsplitter is positioned in the operator's line of sight. The retractable beamsplitter allows the use of non-coaxial illumination without reducing the amount of illumination that reaches the operator when the beamsplitter is retracted from the operator's line of sight. As a result a single system can be used effectively to provide various types of illumination.
