The Meiji Techno MA642 is an SM Plan Strain Free 10X Objective, N.A. 0.25, F.L. 15.6mm, W.D. 6.7mm. Infinity corrected Strain Free Plan 10X Transmitted light Polarizing Upright Microscope Objective is made to the highest Japanese quality and optical standards, utilizing a Finite Tube Lens Design F=160mm. Designed to meet the most advanced Polarizing and Geological imaging requirements. This objective represents the culmination of Meiji Techno’s Optical Japanese technology made specifically for our ML9000, ML9400 and ML9700 Series. This objective offers increased brightness and the highest possible N.A. in its class for maximum light gathering ability. Designed to correct lateral and axial chromatic aberrations over the entire field of view. This objective produces images that are flat, crisp and clear with high contrast and optical resolution. This objective works with a wide array of applications. The stated magnification is based on a Tube lens of 160 mm. DIN Standard mounting threads is 0.7965” (20.1MM) Diameter threads, 36 TPI (Threads per inch), 55° Whitworth. This objective is compatible with all Infinity Corrected Optical systems.

The MA642 Strain-free Plan 10X Infinity Corrected Optical System (I.C.O.S.) upright compound polarizing objective lens is also an option in our ML9000, ML9400, ML9700 Polarizing Upright Series.
