General description:
AJ-OPM07 Operation Microscope (hereafter referred to as simply instrument) is a medical optical instrument with multiple function and applications. The optical system of the instruments equipped with magnification change system which offers 3-step magnification change. Fine focusing can be done by objective fine adjusting focalizer. Four objectives are available for different working distance and magnifications. The illumination system of the instrument adopts a halogen-tungsten lamp and optical fiber for coaxial illumination. The optical system of the instrument is fitted with a beam-splitter, which makes the demonstrator and TV adapter attachable.
The instrument is suitable for various diagnosis, examinations and general microscope operations. Photos or moving photos can be taken during operation. Due to its flexible and stable structure and easy operation, the instrument can be widely used in bone, surgical, cerebrum, ear-nose-throat, ophthalmology and gynecology departments.
