Abstract:
A light combining apparatus using two flat plates for combining at least two incident light beams into a combined light beam using two flat plates, the at least two light beams with wavelengths different from each other entering the apparatus parallel to one another on one side of said light combining apparatus, and spaced from one another at equal intervals comprising:a reflection mirror for reflecting at least one of the at least two incident light beams;at least one filter for transmitting at least one light beam with a specific wavelength and reflecting light beams with the other wavelengths;a medium which is located between the reflection mirror and the filter, through which the at least one transmitted light beam and the at least one reflected light beam pass; andwherein the combined light beam is formed from the at least one transmitted light beam and the at least one reflected light beam before exiting the apparatus.
