OFR stocks this fine line of exceptionally high quality Microscope Objective Lens assemblies, which are ideally suited for focusing laser beams to spot sizes not otherwise achievable with standard optics, as well as for their original use in magnification systems. Our Microscope Objective Lenses are contained in very fine, brushed chrome-plated brass barrels with the industry standard RMS (Royal Microscopy Society) Whitworth screw thread. We also provide our LMO-51 Mounting Plate with this unique thread. These are for use with low-power, visible to near-IR sources. For UV excimer and high power YAG laser applications, please see MicroSpot FOCUSING OBJECTIVES.
