Our Mission
For over four decades, Guernsey Coating Laboratories, Inc. has been working in the area of optical coatings. Beginning in 1982 with one 18” refurbished vacuum system, GCL began depositing the most basic layers on glass substrates.
It was not an accident that GCL has endured and grown. The vision and dedication of individuals willing to go beyond the 9 to 5 workday to create a culture with pride of workmanship and high values; fed by a constant search for knowledge and new ideas, a desire to improve on existing quality, and an understanding that working together is of the utmost importance, has been the unwavering commitment that continues to this day.
While it is never an easy road, the willingness to change with technological advances, solving challenges that a client presents, and taking a project from the initial phase to a successful production stage is a reward for all involved.
GCL has evolved from that one small chamber into several, large multi-vacuum chambers, spanning far beyond the basics by innovating thin film designs, developing applications for substrates other than glass (metals, fiber optics, plastics), and by bringing on instruments to further certify coating performance—all while maintaining our GCL culture of commitment and service.
Commitment to Quality
With optimized coating designs, and stringent handling and cleaning procedures, we have provided our clientele with the highest performance optical coatings possible coupled with some of the lowest defect densities available in the industry for over 40 years. Under Ty Guernsey’s leadership, GCL continues to optimize, expand, and outperform the competition.
The staff at GCL prides themselves on helping our customers solve some of their most difficult application problems by searching out and implementing innovative coating solutions. We will work with you to find the optimum coating solution for your product. When you use GCL, you are getting a company that is committed to providing the attention to detail and service you would expect from your own company’s in-house coating department.
The longevity of GCL’s staff (average tenure is 25 years) has led to a solid trust between GCL and our clients. Not only that, GCL focuses on details:
- Each substrate is accounted for, both in-coming and out-going, inspected and reviewed per our clients’ blueprint.
- Each piece is hand cleaned, evaluated and documented.
- Each run is registered for traceability and logged for future inquiries.
It is of the utmost importance to keep the lines of communication open, working together to overcome challenges and find solutions.
We handle your optics as our own. When you are successful in your endeavors, we are successful.
