Description

The utility model relates to stereoscopic microscopes and can be used as a laboratory or training stereoscopic microscope.

Known stereoscopic microscope manufactured by the domestic industry MBS-10 [1] having a satisfactory image quality. It is a tripod with a focusing mechanism and an optical imaging system. In various modifications, there are lighting systems for transmitted light, or reflected light, or both transmitted and reflected light. As a visualization system, binocular or trinocular nozzles with eyepieces are used. A distinctive feature of this microscope is the use of a single lens forming an image of an object as an imaging system. This image is then split into two, which are recorded using a visualization system. Such a constructive solution reduces the consumer properties of the microscope, the lens is significant in size and weight, and the creation of a system for smooth change of magnification is a difficult technical task. That is why the MBS-10 microscope magnification change system is made spasmodic with partial image loss in time. In addition, the electrical device is external (not built into the tripod of the microscope), which significantly reduces the consumer properties of the microscope.

The objective of the proposed utility model is to eliminate the above disadvantages, increase consumer properties, improve ergonomics and

achieving the convenience of working with a microscope, in particular, eliminating partial image loss in time during the change of magnification.

The problem is solved by the construction of a stereoscopic microscope containing a tripod with a focusing mechanism, a visualization system in the form of a binocular or trinocular attachment with eyepieces, an optical imaging system, which is a dual lens, consisting of two identical optical systems, each of which forms an image of the object independently of the other . In addition, each dual lens optical system allows you to smoothly change the image scale by moving the lenses along the optical axis. For further expansion of consumer properties, a discrete change of magnification in a microscope is provided by the introduction of interchangeable positive lenses in front of a dual lens.

The design of the stereoscopic microscope is shown in Figure 1, where:

1 - subject table,

2 - dual lens

3 - focusing mechanism,

4 - visualization system.

The stereoscopic microscope imaging system is shown schematically in Figure 2, where:

1 - optical systems of a dual lens,

2 - interchangeable positive lenses.

The work on the microscope is as follows (Figure 1). The studied drug is installed on the stage 1. In this case, the object should fall into the field of view of the dual lens 2. Using the focusing mechanism 3, the dual lens is focused on the drug. Observation of the image of the drug is carried out using a visualization system 4.
