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.
