A plastic supercondenser (3D)

Summary

A new construction of a microscope condenser — supercondenser (3D) based on combined illumination has been offered. The condenser consists of three frontal lenses forming an aplanatic system with a numerical aperture of 1.25.

Supercondenser 3D possesses the following advantages:

• 1). It improves the resolving power of the microscope.

• 2). It eliminates optical distortions.

• 3). It forms a plastic image of a three-dimensional object.

• 4). It is simple in use and may be utilized with ordinary microscopes-both for dry or immersion objectives.
