Corr. Objective for Stereo Microscopes Leica PLAN APO 2.0x CORR Objective

With the Leica PLAN APO 2.0x CORR Objective, the refractive index can be adjusted – this way you will have pin-sharp images even if there is a water column of 5 mm between your sample and the objective. The objective enables users to observe and document samples as if the water did not exist.

When observing samples immersed in a watery solution, structures tend to blur especially in high magnification. This is due to the different refractive indices of air (index = 1) and water (index = 1.3). Potentially interesting or important structures may be easily misinterpreted through spherical aberrations that may occur as regular objectives are dedicated to the use with samples surrounded by air only.
