  • Ideal for Bright Field Imaging in UV, Visible, and NIR Spectral Regions
  • Excellent Performance at Nd:YAG Laser Lines
  • Broad Spectral Ranges

Mitutoyo’s NIR, NUV, and UV infinity corrected long working distance 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. The NUV and UV series of objectives have excellent performance at the doubled, tripled, and quadrupled Nd:YAG harmonics.
