The loupe developed by a research team led by Kang Thae Hyok, a researcher at the Faculty of Mechanical Science and Technology, is a portable optical instrument for successful performance of microsurgical operations.
This instrument can be used to raise the accuracy of performing operations by magnifying internal structure of eyes invisible to the naked eye.
It is made up of an optical unit, an illumination unit, a control unit and a glasses frame.
The optical unit is composed of two binocular tubes. Its magnification is 3X, the working distance is 250~300mm and the field of view is 40mm.
1W/3V LED is used for illumination.
The control unit is a device to adjust the distance of axes of the two tubes to the space between eyes. The rack pinion installed in the control body adjusts the space within 50~75mm by the knob.
They established the optimum optical system for convenience and accuracy of operations and solved technological problems arising in the minimization of the size of the instrument.
The loupe they have developed will find wide application in observation of fine structures and micromanipulation as well as in clinical practices like operations on eyes and blood vessels.
