The 12 pages that link to Lens, each with the reason it gives.

• Refractive indexRelated: Curved surfaces with different indices redirect rays to form images.

• RefractionBroader topic: Its curved interfaces use refraction to form images or redirect light.

• OpticsBroader topic: Lenses form images in cameras, spectacles, and microscopes.

• Snell's lawRelated: Ray tracing through lens surfaces applies Snell's law at each interface.

• Geometrical opticsBroader topic: Its focal length and shape determine how it forms images from rays.

• PrismCompared with: A lens typically focuses or spreads a beam; a prism typically changes its direction.

• MirrorCompared with: Lenses are the principal alternative to mirrors for focusing light.

• Achromatic lensNarrower topic: An achromatic lens is a compound member of this broader optical family.

• Ibn SahlNarrower topic: His calculations addressed lens shapes that could focus parallel rays.

• FlashlightRelated: Some flashlights use lenses to focus or broaden the emitted beam.

• RoubaixCompared with: Lens and Roubaix illustrate different industrial foundations within the same region.

• Curved mirrorCompared with: A lens can perform similar focusing, but light passes through it rather than reflecting.
