6A65.70 - Fresnel Lenses

Code Number:
Demo Title:
Fresnel Lenses
Wavelength and Focal Points
Area of Study:
Fresnel Lenses (Plus and Minus), Laser (2 to 5 mW.), Beam Expander lens, and White Paper Screens.

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.
