Optical thin film coatings is an exact science! Penn Optical Coatings understands the physics behind the science; and combines precision engineering with optical expertise to develop, manufacture and deliver thin film coatings with optimal performance. We developed our library of over 7,500 standard and custom optical coatings using our custom-built chambers and coating formulas. Our coatings process combines fundamental thin film physics, expert knowledge of dielectric material properties, and modern deposition technologies. We understand the science of optical coatings – resulting in consistent, repeatable, and durable optical performance of the highest quality.

Optical performance is determined by your application’s requirements. This sometimes results in the need for custom thin film optical coatings. Penn Optical Coatings has the experience and process knowledge to engineer and manufacture a broad range of specialty coatings. In addition to requiring some customization, specialty coatings may also require novel concepts in the design, engineering or process control stages to achieve a desired performance. This may include coating special materials, unique substrate dimensions, and optical properties. Tell us what you need – we’ll make it.

Our greatest resource is our experience. The Penn Optical Coatings team works closely with you to ensure the optimal result for your application.
Optical design software packages like OptiLayer and TF Calc are quite sophisticated, offering multiple optimization routines and production troubleshooting features. Using them requires a depth of experience in the physics behind the formula, and hands-on knowledge of design for manufacturability. Determining the right process to achieve consistent quality and throughput is a significant factor in product cost and performance.
Penn Optical Coatings specially crafts filters and optical coatings from the UV to the IR, for optics from 1mm to 1 meter. Our expertise in silver coatings includes a new formulation proven to improve durability.
