Item # 92-7800
This rigid, shatter-proof acrylic Fresnel lens is ideal for optics activities where gathering light is the priority. Dimensions: 8.5” x 11” x 5/64” (21.6 cm x 27.9 cm x 0.2 cm). Focal Length: 33 cm.
Fresnel lenses are constructed of many (in this case hundreds) of concentric grooves. These grooves are essentially cross-sections of traditional lenses collapsed into each other. The result is a versatile lens with a large surface area, but without the thickness of a traditional lens with a similar surface area. Use this lens for a range of light and optics activities and in conjunction with Arbor Scientific’s Introductory Optical System (92-7700).
