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
  • Backup halogen lamp 12V/10W
  • Matte glass stage
  • Double-sided black and white stage plate
  • Rubber eyecups

hi! What diameter of the view field does this microscope have? Is it equal to 5st microscope?
Customer service:
Levenhuk 5ST has larger field of view (as it has bigger working distance and objective lens).
Robert Fierro (2014.09.02)
This microscope is perfect for studying rocks, minerals and salt crystals. It provides quite high magnification, bright and clear images, has a very convenient stage, smooth bright illumination. A great advantage of the microscope is its large working distance. Eyes do not get tired while working with the instrument, focusing system is really smooth. Great instrument! It is really functional and perfectly suited for professional use. The price is totally reasonable, Levenhuk 3ST is the golden mean among stereo microscopes. The main difference of this improved model is its 45 degrees inclined binocular head. It allows for lengthy observations without any discomfort and eye strain. All optical elements are made of quality highly transparent glass that gives you true color, sharp images. Thanks to its large working distance of 57 mm and sharpness control wheel you can study quite large objects, which makes this microscope suitable for an extensive range of applications. For the most comfortable observations the distance between microscope's eyepieces can be adjusted within 22 mm range. Levenhuk 3ST also has upper and lower halogen illuminations. Durable and economical halogen lamps allow you to conduct your studies even in low light conditions.

Greetings! What is the eyepiece barrel diameter of the microscope? Do you have 5x eyepiece suitable for this model?
Customer service:
Unfortunately additional eyepieces suitable for the Levenhuk 3ST microscope are currently not available in our store.
Kevin Robertson (2014.01.02)
Good evening! Tell me please does this model have an ability to adjust interpupillary distance?
Customer service:
Unfortunately, Levenhuk 3ST model doesn't have the interpupillary distance adjustment. Please consider Levenhuk 5ST Microscope: , which interpupillary distance may be adjusted within 54-76 mm (2.1-3 in) range.
Thomas McDonald (2013.08.07)
Hello! I want to know which microscope is better for studying samples of minerals, subsurface rocks, salts crystals, this one for $270 or the previous model for $150. I can see that this one is more capable and convenient (but is more expensive), but still which one is better?
Customer service:
Both are perfect for this job, but Levenhuk 3ST Microscope has more features and advanced kit.
Carol Dakis (2013.06.12)
Hello again! Can a 7 y/o kid use this microscope? Isn't the interpupillary distance too large for a kid? Which microscope would be better for a kid: this one or Levenhuk D50L Digital Microscope? Observed will be transparent samples and different objects (small rocks, sand grains...)Thank you for answers
Customer service:
The Levenhuk 3ST Microscope is designed for professional research and is meant to be used by specialists in different spheres: jewelry, geology etc. It is also possible to observe transparent samples with this microscope. Levenhuk D50L Microscope NG is more appropriate for the young researcher.
