Mitutoyo LCD Plan Apo NIR & NIR HR Objectives (20x–100x) – Infrared-Optimized, Long Working Distance Optics

$4,520.00$16,400.00

The Mitutoyo LCD Plan Apo NIR and NIR HR series deliver outstanding performance across the near-infrared (NIR) spectrum, optimized for inspection, metrology, and failure analysis in silicon, MEMS, and other IR-transparent materials. Covering magnifications from 20x to 100x, these objectives provide high numerical apertures, long working distances, and minimal aberration—making them ideal for laser-based alignment, backside wafer inspection, and biological IR imaging.

The HR (High Resolution) variants push the limits of clarity and detail, especially at 50x and 100x, offering sharper, more contrast-rich imaging while maintaining infrared compatibility. Whether you’re working with IR lasers, spectroscopy setups, or NIR fluorescence, this series ensures precision and flexibility at every magnification.

Description

The Mitutoyo LCD Plan Apo NIR objectives have the world’s longest working distance and an infinity correction optical system for excellent clearance between the lens surface and the workpiece surface. These objectives are compensated and suitable for high-power observation through LCD glass of 0.7mm thickness.

• Ultra-long working distance makes it possible to observe workpieces that are usually hard to focus because of awkward projection
• Plan apochromatic objective provides a flat, chromatic aberration-free image throughout the field of view, making it suitable for any type of microscope
• Objective design enables high-power observation through a cover glass
• Specially designed objectives are available with correction for near-infrared radiation and various thicknesses of LCD glass
• The mounting screw threads of objectives are designed to conform to JIS B-7141-1988
• Magnifications are available in 20x and 50x
