S. Plan Achromat LWD 40X objective, ∞/0, N.A. 0.65, F.L. 5.0 mm, W.D. 0.78 mm
This Meiji Techno MA348 S. Plan Achromat LWD Phase 40X VT Series Microscope Infinity Objective is made to the highest Japanese quality and optical standards, utilizing an Infinity Tube Lens Design F=200mm. Designed to meet the most advanced metallurgical imaging requirements. This objective represents the culmination of Meiji Techno’s Optical technology. 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 produce 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 200 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 System.
The MA348 S. Plan Achromat LWD Phase 40X objective lens is also an option in our VT Series.
