1× Mitutoyo M-Plan Apo Objective Lens

Description

The Mitutoyo 1× M-Plan Apo Objective Lens (part no. 378-800-12) is a high-performance, plan-apochromatic objective designed for advanced imaging and integration into vision systems. Manufactured to exacting standards, Mitutoyo objectives are widely recognised as the industry benchmark for high-resolution microscopy and machine vision applications.

As part of the M-Plan Apo series, this lens delivers a flat image across the entire field of view while correcting for chromatic aberrations across three wavelengths (red, blue, yellow). The infinity-corrected optical design makes it easy to integrate into custom optical systems, while long working distances provide flexibility for sample handling and inspection setups.

Ideal for brightfield observation in the visible spectrum, the Mitutoyo 1× M-Plan Apo ensures consistent clarity, precision, and reliability in demanding laboratory, research, and industrial inspection environments.
