Refurbished Leitz Objectives for a range of microscopic applications.
It can be said that the quality of Leitz microscope objectives lenses are the best ever made. We have a selection of Leitz lenses from a range of microscopes. More information is available for these lenses and advice can be offered to suit your application.
Some of the lenses available are the highest quality apochromat type.
These lenses focus three wavelengths to a common focus almost totally removing axial chromatic aberration.
They have a higher NA than semi apochromats and produce the highest quality images.
A problem with both apochromats and semi apochromats is a pronounced field curvature requiring constant refocusing to ensure a sharp image.
This situation is not acceptable for video capture of images and in most cases plan objectives are used to provide correction in most categories.
