Optics materials: Glass versus Polymers

Optics materials: Glass versus Polymers

Optical elements are made from various kinds of materials. Optical materials are usually transparent models, meaning materials with good light transmission in some spectral ranges with little absorption or scattering of light. However, absorption could also be used...

Lens for LED optic needed?

When we think about an LED optic we think about a clear plastic lens that is on top of the LED to focus or spread the light. A lens for LED will function as an optic to collect light and magnify its intensity towards the target. Primary optics and secondary optics A...
Refractive index of plastic

Refractive index of plastic

The refractive index, also known as index of refraction or refraction index, is a number which describes how fast light travels through the material. In this article we will take a closer look at refractive indices, refraction, total internal reflection and the...

Advantages of optical polymers

Highly transparent organic polymer materials can be used as optical polymers for a range of applications, including illumination. These optics are known as polymer optics, or plastic optics. Polymer materials Polymers are one of the most used material types in the...
