Description

Product Overview

Up for sale is a highly specialized, industrial-grade Mitutoyo M Plan NIR 5x near-infrared objective lens.

Renowned in the semiconductor and laser-processing industries, the M Plan NIR series features superb plan-apochromatic optical design. It provides exceptional chromatic aberration correction across a broad spectrum, from visible light (436 nm) to the near-infrared region (1064 nm). Designed for flat, distortion-free images, this lens is optimized for infinity-corrected systems with a reference tube lens focal length of f=200 mm.

It features an ∞ specification (designed for specimens without a cover glass), making it the perfect choice for wafer inspection, laser trimming/repair, silicon backside imaging, and custom optical engineering setups.
