Monochromatic aberration

From Wikipedia, the free encyclopedia

In optical apparatuses such as curved mirrors, lenses or prisms, chromatic aberrations, i.e., unintended separation of colors, may occur. However, when optical aberrations distort monochromatic light the effect is called monochromatic aberration. A convex lens can be simply considered angles of prism that has different refracting angles

There are five known monochromatic aberrations:

  1. Spherical aberration
  2. Coma
  3. Astigmatism
  4. Curvature of field
  5. Distortion (optics)
