Micro Stepper Motors Bring Pictures Into Focus
Electro Mechanical Systems has supplied Precistep micro-stepper motors to Life Optics to allow it to develop a compact, reliable and light-weight head-mounted microscope. The result was high-precision technology in the smallest possible space. Each system has two motors, one 8mm diameter and one 10mm, which provide dynamic zoom and focus controls, delivering the high precision and accuracy required for this demanding application. In the basic microscope version, available as Varioscope AF3, users can move freely in a working distance of 300 to 600mm. The foot-operated zoom function allows infinitely variable magnification from 3.6 to 7.2. The field of vision is 30 to 144mm and the pupillary distance can be individually adjusted to each user. The Varioscope M5 provides an extendible modular optical system; changeable oculars extend the magnification range and integrated lighting addresses shadows. With an optional video camera, procedures carried out by the user can be precisely record...
