MA872 Plan Achromat Epi 20X Objective ? for MC-40, MC-50, MC-45, MC-55, MCS-40 , MCS-50, MT7000, MT8000 & IM7000 Series

N.A. 0.40, F.L. 10.0mm, W.D. 5.20mmThis Meiji Techno MA872 Plan Achromat Epi 20X  Metallurgical Upright & Inverted 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 MA872 Plan Achromat Epi 20X metallurgical objective lens is also integrated in our MC-40, MC-50, MC-45, MC-55, MCS-40, MCS-50, MT7000, MT8000 & IM7000 SeriesWhen designing objectives it is critical for Meiji Techno Japanese Engineers to set the ultimate resolution limit of the optical microscope. The important factors is to include the wavelength of light used to illuminate the specimen sample, the angular aperture of the light cone being captured by the objective and as important is the refractive index in the object distance between the objective front lens and the specimen. Resolution can be measured as the minimum detectable distance between two closely spaced specimen points of interest.
