20X T0.7 Mitutoyo LC Plan Apo NIR Infinity Corrected Objective

Product Details Ideal for Brightfield Imaging and Laser-Based Applications through LCD Glass Excellent Performance at Nd:YAG Laser Lines Compensate for Cover-Glass Thickness of 0.7mm or 1.1mm Mitutoyo NIR, NUV, and UV LCD Infinity Corrected Objectives combine the benefits of the standard M Plan Apo and M Plan Apo SL series objectives with enhanced spectral ranges. The NIR objectives are corrected from 480 to 1800nm, making them ideal for semiconductor and telecommunication inspection, or for laser cutting with common Nd:YAG lasers. The HR series offers an increased numerical aperture, providing smaller spot sizes and higher resolution. Mitutoyo NIR, NUV, and UV LCD Infinity Corrected Objectives compensate for common LCD glass thicknesses. The NUV and UV series of objectives have excellent performance at the second, third, and fourth Nd:YAG harmonics of 532nm, 355nm, and 266nm respectively.
