Demo Title: Fresnel Lenses
Condition: Good
Principle: Wavelength and Focal Points
Area of Study: Optics
Equipment:
Fresnel Lenses (Plus and Minus), Laser (2 to 5 mW.), Beam Expander lens, and White Paper Screens.
Procedure:
Clean the Fresnel lenses with plastic polish and a soft cloth when necessary. Put the beam expander on the laser and direct this expanded beam onto the Fresnel lens. Observe the focusing properties and characteristics.
