Description

The Mitutoyo 50× M-Plan Apo HR Objective Lens (378-814-4) is designed for microelectronics, semiconductor, and fine-feature inspection where maximum resolution is required. With a 0.75 NA and 0.3 µm resolving power, this HR lens captures intricate detail at 50× magnification.

Despite its high NA, it maintains a practical 5.2 mm working distance, ensuring compatibility with a range of setups. The plan-apochromatic, infinity-corrected design ensures colour accuracy and flat-field imaging across the visible spectrum.
