Stereomikroskoobid

Stereomikroskoobid, also known as dissecting microscopes or stereo microscopes, are optical instruments that provide a three-dimensional magnified image of a specimen. Unlike compound microscopes, which use a single objective lens to create a magnified, flat image, stereomicroscopes employ two separate optical paths, each with its own objective lens and eyepiece. This binocular design allows each eye to view the specimen from a slightly different angle, producing a stereoscopic effect that reveals depth and texture.

The primary advantage of stereomicroscopes is their ability to observe relatively large and opaque objects, such as insects, rocks, or electronic components, without the need for extensive sample preparation. They typically have a lower magnification range compared to compound microscopes, usually from 10x to 50x, making them ideal for examining the surface details of specimens. The working distance, the space between the objective lens and the specimen, is also considerably longer in stereomicroscopes, allowing for easier manipulation of the sample during observation and dissection.

Stereomikroskoobid are commonly used in educational settings for biology labs, in industry for quality control and assembly of small parts, and by hobbyists for tasks like coin or stamp collecting. Their robust construction and ease of use make them a versatile tool for a wide range of applications where a magnified, three-dimensional view is beneficial. Illumination is typically provided from above the specimen (reflected light) or from below (transmitted light), or a combination of both, depending on the nature of the object being viewed.
