Description
A compound lens designed by Ernst Abbe as a substage condenser for transmitted light, brightfield microscopes. An Abbe condenser can consist of one to three lenses providing a combined numerical aperture range of up to 1.3 that makes it useful for medium- to high-magnification objectives. However, the condensers are not suitable for oil immersion objectives (McCrone and Delly 1972). In most cases, the Abbe lens system is not corrected for Spherical aberration or Chromatic aberration.
