General description.
Operation Microscope Model (hereafter referred to as simply instrument) is a medical optical instrument with multiple function and application. The optical system of the instrument equipped with magnification change system which offers 3-step magnification change. Fine focusing can be done by objective fine adjusting lever. Two objectives are available for different working distance and magnification. The illumination system of the instrument adopts coaxial illumination with 10W LED light source. The optical system of the instrument is fitted with a beam splitter, which makes video camera adapter and demonstrator attachable. The demonstrator is optional.
The instrument is suitable for various diagnosis, examination and general microscope operation. Photos or moving photos can be taken during operation after connecting CCD camera or digital CCD camera with instrument. Due to its flexible and stable structure and easy operation, the instrument can be widely used in ear-nose-throat, ophthalmology, gynecology and dentistry departments.
