The Importance of Antireflection Coatings for Optics @edmundoptics

Uploaded May 2025 | Updated September 2026, 2 weeks ago

Why are antireflection coatings so important for optics?

These unwanted reflections off of glass surfaces are called Fresnel reflections

They can lead to a lot of light being lost in a system with many different glass lenses, windows, prisms, and other optics

Antireflection coatings minimize unwanted reflections so that the maximum amount of light transmits through an optical system

There are lots of other laser demos like this on the Edmund Optics YouTube and TikTok channels

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