For over 50 years, Coursen Coating Labs has been an industry leader in the optical thin film coating industry. We pride ourselves on working to find innovative and cost-effective ways to improve our customer's products.


In 2009 we changed our name to Coursen Coating Labs Inc.  Coursen is a leading optical manufacturer that sells to OEM customers and dealers worldwide.


Today's manufacturers are constantly striving to improve the performance of their products and differentiate themselves from their competition. Coursen Coating Labs can help your company gain that competitive edge by improving the performance of your optical system.


Coursen Coating Labs produces vacuum-deposited and sputtered coatings for UV, visible and IR applications and offers an extensive line of stock and custom coating designs.  We produce a wide range of specialty coated products including coatings for high-intensity lamp reflectors, and mini mirrors for use in telecommunications. We also produce corrosion-resistant gold coatings for use in fiber optics, telecommunications, and military applications. In the UV industry, Coursen Coating Labs' specialized mirrors and filters are used to improve the brightness and output of existing UV optical systems.  Our solderable coatings, which are produced using Coursen's proprietary sputtered process, allow the glass to be soldered to metal for military, aerospace and other applications requiring extreme reliability.
