A technique for collimating light from a Light Emitting Diode device involves emitting light from an LED die, collimating the light with a parabolic reflector, and further collimating the light with a lens. The system includes a half-adder circuit associated with each separate bit position i in A and B. The system memory structure includes a user interaction module, which allows a user to select image objects, an image object selection module for interpreting imprecise image object selection paths, and data memory. In some instances, the sheet metal sidewall shell has only one seam that may or may not be a welded seam. In order to provide the second illumination mode, the system has a focusing lens inserted into the path of the illumination beam in such a way that the illumination beam is focused into the back focal plane of the microscope objective. Here, the light transmitting member includes a cover member that covers the semiconductor light emitting device and transmits at least apart of the light generated by the semiconductor light emitting device, and a deflection member that covers front of the semiconductor light emitting device and deflects forward a part of the light generated by the semiconductor light emitting device.
