Abstract
An illumination system for diascopic microscopy comprises a computer (610) with memory (625), a graphics program (605), a display driver (615), and graphical display (600). The display is positioned between a microscope's light source (105, 704) and condenser (110). When activated, the illumination system causes the display to display a predetermined pattern which the light source projects onto the condenser and is then focused by the condenser on a subject (125) to be examined. In conjunction with the microscope's light source, the illumination system emulates the illumination techniques of bright field, dark field, oblique, polarized, monochrome, modulation contrast and phase contrast illuminations.
