In the high-stakes world of clinical microscopy, few microscopes have made an impact as massive as the Olympus BH2. If you were using a microscope in the late 1970s or early 1980s, chances are you were looking through the eyepiece of a Leitz Laborlux or an American Optical (AO) 110. These two powerhouses dominated the market—until the Olympus BH2 came along and changed the game forever.

How the Olympus BH2 Dethroned the Competition

When Olympus introduced the BH2 series in the 1980s, they weren’t just launching another microscope—they were declaring war on the industry leaders. The Leitz Laborlux had long been the go-to for clinical and research applications, while the AO 110 represented American Optical's best shot at holding onto dominance.

But Olympus had a different vision. They designed the BH2 with precision, durability, and modularity in mind, aiming to match the optical performance of high-end overseas products while offering unparalleled customization options. It worked. The BH2 quickly became the microscope of choice for clinical professionals, relegating the AO 110 and Leitz Laborlux to the sidelines.

What Made the Olympus BH2 So Special?

• Legendary Durability: This microscope was built to last. Even decades later, many BH2 units are still in use—a testament to their superior engineering.

• Modular Design: Olympus gave users flexibility with a long barrel objective lens (45mm focal length/160mm mechanical tube length), making the BH2 adaptable for bright field, fluorescence, and phase contrast applications.

• Superior Optics: The BH2 was designed to rival the best in the world, and it succeeded. Many professionals still swear by its crisp, clear imaging.

• User-Friendly Features: From easy bulb replacements to smooth stage adjustments, Olympus made sure that working with the BH2 was a seamless experience.

Common BH2 Issues and Fixes

Even the best microscopes need maintenance, and the BH2 is no exception. One of the most commonly failed components is the BH2 gear box, which can wear out if neglected. (Get a replacement here: BH2 Gear Box).

The Legacy of the Olympus BH2

The BH2 series was eventually replaced by the Olympus BX series, but its reputation remains untouchable. The BX microscopes continue Olympus' tradition of excellence, but many professionals still prefer the BH2 for its unbeatable combination of durability, precision, and ease of use.
