What are Optical Coatings?

What are Optical Coatings?

Light is a fascinating phenomenon, shaping our world and influencing everything we see. At Diamond Coatings, we harness the power of light through a remarkable technology: optical coatings. These thin layers of specifically chosen materials applied to optical components like lenses, mirrors, and filters dramatically alter how light interacts with the surface.

But what exactly are optical coatings, and how do they work their magic?

Imagine a ray of light striking an uncoated lens. A portion of the light bounces back (reflection), while the rest travels through the lens (transmission). However, the reflection can cause glare and unwanted light scattering, while some light can be lost due to absorption within the lens material.

Optical coatings come to the rescue! These microscopically thin layers, typically ranging from a few nanometers to several micrometers thick, are deposited onto the optical surface using specialized techniques like sputtering. By carefully selecting the material and precisely controlling the thickness of the coating layers, we can manipulate how light interacts with the surface.

Here’s how it works:

Anti-Reflective Coatings (AR Coatings): These coatings minimize light reflection, allowing more light to pass through the lens. Imagine a camera lens with an AR coating – you capture clearer images with less glare and improved overall image quality.

Reflective Coatings: In contrast to AR coatings, these coatings maximize reflection for specific wavelengths of light. Mirrors utilize reflective coatings to create a clean and efficient reflection.

Filter Coatings: These coatings selectively transmit specific wavelengths of light while blocking others.
