Illumination
Optics
Fiber Optics –
Provides a means of transferring light to
hard-to-get places and small restricted areas, or of illuminating a large
area with uniform illumination. The source of light is typically
a quartz halogen bulb that is coupled to a bundle of optical fibers.
The efficiency is quite low. The fibers can be ended in different
geometries to produce different shapes and/or multiple light beams.
Condenser Lenses – They are used in combination with
field lenses to transfer light with maximum efficiency to a
desired area.
Diffusers – A diffuser – e.g. ground or opal glass is illuminated
by light source and then the diffuser is imaged out to the area
of the object. Incoherent fiber-optic bundle, where fibers at the
exit are distributed differently then at the entrance, can produce
more uniform diffused light. Diffuse illumination of specular surfaces
allows imaging without bright reflections.
Collimators – They move the light source optically far
from an object by collimating the light.
