Mizuho LCE

Olympus released the Mizuho LCE in 1935, 10 years after the first Mizuho brand launch. The Mizuho LCE was the company's first large, binocular biological microscope, marking a major step forward from the previous monocular models. The microscope featured an apochromatic objective lens that provided high resolution and little chromatic aberration, plus a revolver to switch between four lenses. The maximum magnification was 2000x. The microscope used a highly accurate mechanical stage. Overall, the Mizuho LCE provided greatly improved ease of use.
Olympus had already produced another binocular microscope—the Yamato LCD—that used an apochromatic objective lens. The microscope head was replaced with a monocular head when taking photographs using these models.
