OPTICAL DEVICE USING BOTH ELECTRO-OPTICAL (EO) AND INFRARED (IR) LIGHT

摘要

The present invention relates to an optical device having a compact size. To this end, the optical device using electro-optical and infrared light according to the present invention includes: a lens barrel having a circular drum shape and an opened side; a main reflecting mirror disposed on a side opposite to the opening within the lens barrel; a secondary reflecting mirror disposed within the lens barrel to receive light reflected by the main reflecting mirror; a splitter disposed between the main reflecting mirror and the secondary reflecting mirror so that light reflected by the secondary reflecting mirror is incident into the lens barrel, and the incident light is split into visible light and infrared light; a visible light analysis part closely attached to the lens barrel to read the visible light incident from the splitter; and an infrared light analysis part closely attached to the lens barrel to read the infrared light incident from the splitter.
