Bright Field Microscopy - Light Path

Light Path

The light path of a bright field microscope is extremely simple, no additional components are required beyond the normal light microscope setup. The light path therefore consists of:

  1. a transillumination light source, commonly a halogen lamp in the microscope stand;
  2. a condenser lens which focuses light from the light source onto the sample; and
  3. oculars to view the sample image.

Bright field microscopy may use critical or Köhler illumination to illuminate the sample.
