Plano Cylindrical Lens, Concave - Power Diopter -17 - 50 x 50mm

This cylindrical Plano lens is useful for demonstrating the basic principles of light refraction and the way that different types of lenses can be used to bend or redirect light and show how light passing through the lens is bent in different directions depending on the angle at which it strikes the lens surface. Great for helping students to understand the basic principles of optics and how lenses can be used to correct vision impairments.
This cylindrical Plano concave lens measures 50mm x 50mm (2" x 2"). This lens has a -17 power diopter and is made of high quality, optically worked glass. Highly polished for maximum performance and features ground edges for added durability. Excellent for physics classroom. Ideal for demonstrations in optics and light refraction.
