M Plan Apo is a standard in the microscope optics industry. Apochromatic lenses are designed to correct for red, blue, and yellow light, while ordinary apochromatic lenses only correct for red and blue light, and all lenses are stress free, resulting in better color reproduction. The Plan specification objective lens can compensate for surface distortion, point distortion, and other distortions in the image.

The long working distance apochromatic objective lens or APO objective lens has an excellent optical system. This objective lens can provide a flat, monochromatic aberration-free (almost no chromatic aberration) image in the entire field of view. It is suitable for various microscopes and can be used with A series of zoom lenses from MSS are combined into a high-performance zoom lens system, which is ideal for semiconductor product inspection, flow cytometry or other high-efficiency high-magnification applications. Its advanced design provides very high resolution and outstanding contrast. Its resolution can be from 5 microns to 0.34 microns.
