Why Antireflection Coatings Are So Important For Lenses

How NOT to Look at the Eclipse - No Cameras/Telescopes!

$The Magic of GRIN Lenses GRIN lenses bend light completely differently than normal lenses Rather than using curved surfaces, the material of the lens itself changes gradually throughout the lens This causes refraction (the bending of light) to not just be done at the lens surfaces, but all throughout the inside of the lens GRIN lenses can be much smaller than normal lenses, resulting in very compact and lightweight optical systems Edmund Optics sells a wide variety of both conventional and GRIN lenses for all kinds of optical applications #optics #science #stem #physics #engineering #photonics #lens$
