This is a set of 4 plan-fluor objective lenses for high-resolution biological and fluorescence applications. The set includes 4X, 10X, 40X, and 100X lenses. Semi-apochromatic optical corrections improve resolution and color accuracy by realigning blue, green, and red wavelengths. Plan field corrections further improve image quality by providing edge-to-edge sharpness. Along with improvements in resolution, the optics provide better transmittance in the ultraviolet and near-infrared bands for use in fluorescence microscopy.

The lens is designed for use with AmScope upright, infinity-corrected microscopes, as well as other microscopes using RMS mounts and 45mm parfocal distance.
