Kopp Glass was founded in 1926 from the reorganization of the Pittsburgh Lamp, Brass and Glass Company. The strength and core competency of the original company was the ability to develop and mold beautiful glass lamps and tableware in a wide range of colors. Those same core competencies are among the competencies that make Kopp the unquestionable leader in its field today.

Kopp Glass expanded into the industrial and technical glass market in its early years through the development of “selenium red” glass. This glass became the standard for railroad signal lighting and the rest is history.

Through the years, Kopp Glass has continued to make important contributions in the aerospace, industrial, scientific, transportation, and other markets. In the latter part of the 20th century, our glass scientists developed monolithic night vision (NVIS) compatible filters used in many of the world’s military aircraft for night operations. These filters allow pilots to operate with night vision goggles without being blinded by the instrumentation lighting.

In the early 1980’s, Kopp Glass entered the filter glass business. This product line continues to be an important and strategic part of the company today. We continue to add new products to the line and to improve product quality to meet the needs of our customers.

As markets and products have changed over the years and so has Kopp. Today our products can be found all over the world. We continue to upgrade our facility and manufacturing capability and to develop our technical expertise. Every day we use our expertise to develop innovative and unique solutions for our customers that create value and differentiate their products.
