Levenhuk 3ST is a reliable stereo microscope with a binocular head inclined at 45 degrees. This design allows for comfortable observations for extended periods of time without any muscle strain, and no additional stress to the eyes due to the binocular head (comparing binocular microscopes to microscopes with monocular heads). The optics in this model are made of high-quality glass with special coating, so the rendered images are sharp and the colors are true.

Levenhuk 3ST is the standard model of the Levenhuk stereo microscope product range. This range of microscopes is perfect for professional research and casual observations by biologists, geologists, jewelers and many others. The 3D image of the observed object rendered by this microscope allows you to study the object in great detail and measure its dimensions with unprecedented precision.

This binocular microscope has a relatively long working distance of 57 mm (2.2 in) that allows you to study flat specimens as well as rather large objects.

The built-in illumination sources (upper and lower) allow you to use your microscope even in the dark. Halogen lamps used are highly economical and will serve you well for a considerably long time before you have to change them. For even more comfortable observations, you can rotate the stage plate so that it faces either the black or the white side upwards, and besides, hold a specimen in place with the useful stage clips.

Levenhuk 3ST Microscope comes with WF10x eyepieces and rotating objective with magnifications of 2x and 4x.
The kit includes:
- Levenhuk stereo microscope
- Binocular head
- WF10x eyepiece - 2 pieces
- Rotating objective: 2x, 4x

Is it worth purchasing a stereo microscope?
A stereo microscope is a very popular optical tool among radio amateurs, jewelers and explorers of the micro world. Its main distinctive feature is that it delivers a three-dimensional image. Sometimes stereoscopic microscopes are confused with regular binocular microscopes, but they have different optical designs.
In a classic microscope with a binocular head, only an objective lens is used for forming an image. The received image is just duplicated to two eyepieces. The transmitted image is only one, but you can view it with both eyes simultaneously. In stereo microscopes, two objective lenses are used for forming an image - one per each eye. In fact, we receive two independent optical channels, enabling us to observe a stereoscopic image. This optical scheme is called Greenough scheme. It has recently become widespread.
Children and adolescents enjoy working with a stereo microscope due to its simple operation. This is not surprising: you can study coins, rocks and any other artefacts of the world around us that can be of interest to a young explorer. A stereoscopic image is essential in studying electronic circuits, watch mechanisms, crystals, minerals and artworks. It allows for detailed studying of large objects' structure and detecting the surface defects. Such a stereo microscope is recommended for purchase to an amateur microbiologist. It will be very useful for preparing microscope slides.
Levenhuk ST series microscopes will be perfect for any purpose. The series includes four stereoscopic microscopes, which differ in magnification range, working distance and type of illumination. The microscopes are designed for amateur and professional users and also will come in useful for a home hobby.
