LWD Plan Epi Objective 20X, N.A. 0.40, W.D. 11.0mm, F.N. 24
This Meiji Techno MA920 Plan LWD 20X, dry Metallurgical Upright Brightfield Microscope Objective Infinity 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 offer 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 MA920 S. Plan LWD E20X upright compound metallurgical objective lens is also an option in our MT7000 and MT8000 Metallurgical Upright Series
