High-quality and precise lenses are required – especially in microscopy – in order to obtain maximum image information. This is not the only area where ZEISS products have been setting new standards for over 170 years. A key detail here is the front lens, which is only a few millimeters in size. Thanks to a manufacturing process that has been specialized over decades, we can produce these special lenses sharp-edged with an aperture angle of up to 178°. In doing so, we are always adapting our production techniques to new possibilities in order to refine the result further and further.
