Plan-Apochromat SF25

This first-class series of objectives with excellent correction and extremely high apertures provide a maximum of resolving power, color purity, contrast and image flatness for observation and photomicrography. The enormous resolving power reveals structures that otherwise can not be discerned. As image brightness in fluorescence microscopy increases with the power of four of numerical aperture, Plan Apochromat objectives are excellently suited to fluorescence applications.
