Microscope MI-1

The inverted microscopes MI-1 and MI-1T are intended for inspection and research in metallography and other fields of science and technology.
The microscope's design is highly ergonomic. It allows adjusting the eye base and carry out the dioptric adjusting for operator's eyesight in broad range. The magnification change is made through an electromechanical drive. An option is envisaged for fine and coarse accelerated displacement of the object stage and for easy switching between the modes. All this makes the work at the microscope easy.

Object observation modes:
 bright and dark fields by reflected light (MI-1);
 bright field in transmitted light, light and dark field in reflected light (MI-1T);
 polarization contrast by reflected light.

On the request the following parts can be supplied (optional):

  • Objectives with enlarged focal length  - 5 (17mm), 10 (22,4mm), 20 (12,8mm) ; 
  • Two eyepieces 15x, two eyepieces 12.5x (one of them with grid);
  • Transmitted light illuminator
  • Set of polarization filters reflected light;
  • Set of changeable light filters transmitted light;
  • TV-adapter;
  • Photo adapter.

On the base of the microscope a complete complex can be mount: microscope, adapter, TV-camera, digital photo camera, computer (monitor), software.

Universal inverted optical microscope with screening of images on personal computer or video monitor can be shipped

Microscope is intended for use in metallography researches in industry, biological scientific researches as well as in other field of science and engineering.

It is possible to mount on additional optical channel different digital cameras with proper adapters.

For operation with different clear objects in biology and other different fields of science and engineering this microscope can be equipped with an additional transmitted light illuminator which is supplied with a set of changeable light filters transmitted light. Operating mode of the transmitted light illuminator using method of polarization contrast is envisaged.
