U.S. MICROSCOPE COMPANY MICROSCOPES OBJECTIVES

USMCO MICROSCOPE OBJECTIVES

All U. S. Microscope Objectives are Plan Aprochromatic and are infinity corrected, using direct long working distance with the highest performance.  Optical coatings are optimized between 450 and 650 nm with no more than 0.5% transmission variation.

Abbreviations:  M – Magnification, N.A.- Numerical Aperture, WD – Working Distance, f – Focal Distance, R – Resolution, DFD – Diffraction Focal Depth, MFG TL – Manufacturing Tolerance.  Items 6 and 7 are Super Long Distance, and items 8 through 11 are Near Infra Red.
