Quality CUSTOM

Precision Optics


Our History

In 1944, Joseph Roland Cumberland opened Cumberland Optical Company in Silver Spring, MD, after training in his craft at the Washington Navy Yard. In the years following, the company expanded, became J.R. Cumberland Incorporated, and moved to its current location in Marlow Heights, MD. In 1959, J.R. Cumberland Inc. began a collaboration with Questar Telescopes that continues today. Roland's sons Stephen and Dwight Cumberland became owners of the company upon his retirement in 1997. In 2015, 30-year employees Robert Kautz and William Greening took over as owners, and continue the legacy of Roland's and his sons' dedication to providing reliable service and products to their clients. 

Our Mission

Every order is different-- it's our job to understand your specific idea for a product and make what you need. Since 1944, J.R. Cumberland has provided our clients with exceptional custom optics, offering a small business experience with close collaboration to make sure we get it right. Our dedicated opticians have decades of experience, and we offer a variety of materials and services to fit a range of specifications.
