How to Customize Glass for New Light-based Technologies

By Kopp Glass | August 19, 2016

Light-based technologies continue to advance at an impressive speed. They’re being used in new and emerging applications where the ability to control light is critical for success.

The Definitive eBook on The Thermal, Optical, and Mechanical Properties of Glass

By Kopp Glass | July 22, 2016

Designing a glass lens, filter, or component? Not sure how to best meet your performance requirements? Our comprehensive eBook on the properties of glass can help you.

2 Common Glass Manufacturing Methods: Batch and Continuous Melting

By Kopp Glass | April 7, 2016

Differences in individual glass melting practices are driven by the scale and scope of the manufacturing, the glass composition needed, the downstream processes involved, and the ultimate product quality required. In this article, we’ll review two common glass manufacturing methods: continuous and batch melting.

Chromaticity Basics: Factors, Calculation, and Application

By Kopp Glass | January 11, 2016

Color is a universal language. At traffic lights around the world, drivers understand to stop on red and go on green. For many signaling applications, including those in the railroad and aerospace industry, operators are trained to recognize and respond to very specific colors.

The Clear Choice: How to Choose the Best Transparent Material

By Kopp Glass | November 12, 2015

There are many transparent materials out there for you to consider when designing a lens for a lighting application. Take a look at the image above; these different transparent materials all look fairly similar don’t they? You may be asking yourself “What makes glasses and plastics so different?

How to Design with LEDs: Iterative Approach Yields Fully Optimized Lighting Systems

By Kopp Glass | October 19, 2015

While the cost of light emitting diodes (LEDs) is decreasing, they are still relatively expensive and their adoption should be carefully considered before making the switch. Optimization of the optic and other system components can reduce the number of LEDs needed and reduce the overall cost of the LED lighting fixture. Solid state lighting (SSL)…

Mechanical Properties of Glass: Design to Survive Stress, Impact, and Abrasion

By Kopp Glass | September 28, 2015

When designing a lens for a harsh environment, you need to choose a material that is resistant to pressure, abrasion, and impact. Some applications, such as exterior aircraft lighting, can push a material to its limits. Exterior aircraft lenses are exposed to smog, dust, and other air pollutants at very high speeds; the resulting impacts…

Challenges of Determining LED Useful Life

By Kopp Glass | September 14, 2015

The transition to light emitting diodes (LEDs) from conventional light sources brings several new challenges to lighting engineers and designers. LEDs are much different than incandescent bulbs, especially in terms of useful life. It’s easy to determine the useful life of an incandescent lamp; if the light goes out, its useful life is over. This…

Optical Properties of Glass: How Light and Glass Interact

By Kopp Glass | August 24, 2015

This is the second article in a three-part series that reviews the thermal, optical, and mechanical properties of glass. We will define common glass properties and explain their application and importance in component design. We often hear from engineers who are evaluating the impact of a design change from one lens material to another. For…

Glass Thermal Properties and Their Role in Product Design

By Kopp Glass | August 5, 2015

This is the first article in a three-part series that reviews the thermal, optical, and mechanical properties of glass. We will define common glass properties and explain their application and importance in component design. It is critical to have a thorough understanding of glass thermal properties when designing with a glass lens or filter. When exposed…
