World Leader in High Performance, Ultra-Durable
Optical Thin Film Coatings

 

 

Deposition Sciences, Inc. (DSI®) produces the most durable, heat resistant and reliable optical thin film coatings in the market. Our exclusive thin film filter coating services and capabilities range from the ultraviolet (UV), through the visible (VIS), near infrared (NIR), shortwave infrared (SWIR), midwave infrared (MWIR) and out to the far infrared (FIR), or the long-wave infrared (LWIR) spectral wavelengths.

For over twenty years, DSI has been providing innovative optical coating solutions for military and aerospace, lighting tasks, telecommunications and data communications, and medical and scientific applications. Offering collaborative product development, standard and custom optical coatings and solutions, we deliver unique thin film deposition technology, proprietary coating processes and engineering excellence for real-world challenges.

COMMERCIAL PRODUCTS DIVISION

Our precision coating methods are achieved using DSI’s unique MicroDyn® reactive sputtering deposition technology and our patented IsoDyn™ low pressure chemical vapor deposition (LPCVD) process. DSI’s precision optical coating technologies allow us to provide components with superior performance that can improve your products and lower your costs. Deposition Sciences offers rapid prototyping and quick manufacturing turnaround. Combining advanced performance, heat resistant coatings with durability and stability at extreme temperatures, DSI can assist you through all stages, from product development to volume manufacturing.

GOVERNMENT PRODUCTS DIVISION

DSI’s Government Products Division is dedicated to providing optical coatings for military, aerospace and space based programs. With decades-long expertise, GPD products include longwave pass, shortwave pass, and band pass filters on exotic materials such as Silicon (Si), Germanium (Ge), Zinc Sulfide (ZnS), Zinc Selenide (ZnSe) and ClearTran as well as optical glasses for systems which operate across the visible, near infrared, shortwave infrared, midwave infrared and far infrared ranges out to 50 µm.

WHY EXTREME DURABILITY?

Many coated products face exposure to extreme conditions such as high heat, temperature fluctuations, severe abrasion, salt fog, high humidity, harsh chemicals, and sub-freezing temperatures, with little or no protection.

DSI took on the challenge of developing a highly advanced system to meet these harsh environments with reliable, highly durable thin films. Over a period of years our R&D and scientific engineering teams designed proprietary systems that produce precision optical coatings with high durability in high volume.

Our first endeavor was to create optical films that could withstand the extreme heat and long service life in lamps such as quartz halogen and metal halide arc systems. These applications require that optical films operate for thousands of hours at temperatures ranging from 800°C to 1000°C. In addition to extremely high heats, the films must survive repeated thermal cycling, from ambient temperatures to operating temperatures, with a cycle time of only a few seconds. This quick heating-cooling action can destroy the integrity of an optical coating. Thus, the IsoDyn™ LPCVD system was born.

After a successful launch of the IsoDyn™ process, we went back to work – this time to develop a system that would produce the same durability as IsoDyn, but with the added benefit of even faster production. The effort culminated in our patented MicroDyn® system. Now DSI has a coating process for virtually every type of optical component, no matter how complex.
