Fixed-focus objective lens MPLAPON series

apochromatic

Our MPLAPON Plan Apochromat objective lens Series provides the highest level of chromatic correction and resolution capability available from Olympus. High level wavefront aberration correction is guaranteed. M Plan Apochromat MPLAPON • Dedicated for brightfield microscopy, simple polarized light and DIC (Differential Interference Contrast). • The Plan Apochromat series provides the highest level of chromatic aberration of the Olympus objective lenses. Guaranteed optical performance (wavefront aberration) with a Strehl ratio of 95% or better. • Compatible with the Olympus autofocus unit, ideal for automating the inspection process. Strehl ratio: Indicates as a percent, the ratio of the proportion of light that an actual optical system can concentrate with respect to the proportion of light concentrated in the image plane (central intensity) by an ideal, aberration-free optical system, with the latter serving as 100%. A higher percentage indicates a higher quality optical system.
