Home / Who We Are

For over 50 years, Dontech has had strong relationships with manufacturers, designers, and engineers — all important partners. We meet our customers' needs by creating custom solutions for fielded units allowing our medical, military, avionic, and industrial customers to work in real world environments. We pay attention to every detail, from the initial development of a product until we're sure that it's performing optimally within its finished application.

Optical Films, Coatings & Components Manufacturer

Areas of Focus
Dontech is an AS9100D and ISO-9001:2015 certified designer and manufacturer of optical filters, laminations and thin and thick film coatings for the precision optics, display, and touchscreen markets. We design, manufacture, and integrate custom components that enhance the performance of optical systems. As your experts in LED, LCD display enhancements, PVD coating solutions, transparent glass coatings, and optical EMI shielding (MIL STD 461, 462, 464) we are positioned to help OEMs, optical manufacturing companies, and Tier 1 DoD contractors that need a partner to see your projects through completion.

Where The Work Gets Done
Our corporate headquarters is located at 700 Airport Blvd. in Doylestown, Pennsylvania, located about an hour north of Philadelphia and two hours southwest of New York City. We have 4 facilities at this campus that are uniquely outfitted and vertically integrated with an extremely broad range of design, test and manufacturing capabilities. We have been designing and manufacturing products in Doylestown, PA for over 50 years.
The Beliefs That Guide Us
It is because of our deeply held beliefs – that the workplace should be a rewarding experience and that we all have an obligation to give back – that we strive to look beyond ourselves by doing bigger things. Dontech’s commitment to helping others is reflected in the many ways our people impact lives every day.

Workplace Culture

Dontech’s commitment to quality, innovation and R&D, and the people who make up our team has guided the company for more than 50 years. We understand that our products are used in mission-critical and life-saving applications, and we have the controls in place to ensure consistent quality, traceability, and performance. We understand that internal and external teamwork are critical for these goals to be realized.

At Dontech, we are committed to building a community based on a foundation of mutual respect while striving to provide an environment that allows our employees to enjoy their work.  Whether it be our yearly celebration of NSPE’s Engineers Week, summer barbeque lunches held outside, employee raffle drawings, or simply the suggestion box in the lunchroom, we are continuously looking for new opportunities to help our employees realize they’re a meaningful part of the Dontech family. We understand the value of an employee’s time both in and outside of work, and we know that no one can run at 100% without the ability to relax and recharge. In addition to our at-work events, we encourage employees to put their families first and work a close second in order to maintain a sustainable work life balance.  Our commitment to meeting our employees’ needs helps us attract and retain a talented team who function together and continue to produce the high-quality products our customers expect.

Our technical staff are industry experts who can help troubleshoot designs to enhance performance and cut costs. We know how expensive it is to requalify a product, so we support product lines far beyond industry standard, saving our customers money. Our commitment to doing all the little things right means you will have the support to accomplish the big things.
