Lenses
| Glossary Of Laser Terminology |
- Lenses are devices that redirect light. in photography, lenses are used to focus an image for the film. holographers use lenses to widen a laser`s beam to illuminate the entire object being holographed.
- Transparent optical devices affecting the wavefront curvature of light
- Spectacles with lenses which have two types of lens combined in the same piece of glass, the top part being used for seeing at a distance and the lower part for reading
