The OMAX Binocular microscope provides students and researchers with a unit that can stand up to more expensive models, but at a price that is under $200. It offers high quality objectives, sturdy metal construction and an intuitive design. It offers a perfect balance between price and quality and can hold its own against higher priced competitors offered by Nikon and Olympus.

OMAX has been manufacturing microscopes for 47 years and is a large and well known Asian manufacturer of a wide range of products.

The Omax 40X - 2000X Lab LED Binocular Microscope (Model # 4331885897, Part # 4331885897, M82ES) is a best seller on Amazon. This microscope came to our attention for several reasons, including its suitabiity for college students, high school students, home school use, clinical examination, labs and for advanced applications. It is also a flexible platform since it is simple to add a digital microscope camera for photographic images or for live video viewing. It also has a darkfield accessory which can shift to a darkfield microscope from a brightfield microscope.

You can see detail on slides such as the nucleus, cell walls and cell membranes. We also know of medical professionals that use it to view tissue, blood urine and fecal samples.

Minor assembly is a non-issue such as inserting the eyepieces and attaching the power supply for the illuminator.
