The M-20X microscope objective has a 20x magnification, 0.40 numerical aperture, 9.0 mm focal length, and 6.0 mm clear aperture. It uses a standard RMS thread, 0.800-36. The objective is corrected for a rear conjugate at 160 mm. The lenses are antireflection coated with MgF2 for the visible spectrum. This M-20x objective is suitable for use with either the Model 900 or 910A spatial filters. M- series microscope objective power is based on a 160 mm tube length. MP = 160 mm/f
