Company History

RL Associates is a small, woman owned business located in Yardley, PA. It was established by Dr. Richard Billmers and Ms. Elizabeth Billmers. Dr. Billmers holds a Ph.D. in physical chemistry with a specialty in laser spectroscopy, and Ms. Billmers holds a Master of Science in analytical chemistry. Prior to founding RL Associates, Inc., their research included combustion diagnostics, characterization of light scattering in ocean water, designing LIDAR systems for ocean water surveillance, and laser induced breakdown spectroscopy for missile counter-measures.

RL Associates incorporated in 1996 and has been faithfully serving our governmental and commercial clients ever since. RL Associates has been awarded four patents, with two still pending, for several optical designs and Lidar components.

As our main focus is research and development, our efforts have been sponsored by the Small Business Innovative Research (SBIR) programs at the Naval Air Systems Team, the Office of Naval Research, NASA, and Department of Homeland Security. In recent years, several of the technologies developed by RL Associates have progressed closer to independent funding by prime contractors as well as insertion in the relevant platforms.

Our work has been successful enough to transition fully half of our Phase II contracts
to Phase III.

Our recognitions include:

  • 2009 featured company in “Highlights”, a NASA publication showcasing
    the successes of its programs.
  • The 2007 National Tibbets award for outstanding SBIR achievement.
  • Featured in the Dept. of the Navy SBIR Success Stories for several
    of our SBIR contracts.


As a vibrant research and development organization, we are constantly seeking self-motivated individuals with 3 or more years experience in the following areas:

  • Optical Ray Tracing and Design using Zemax
  • Mechanical Design using such software as Solidworks or Pro-E
  • Control of laboratory equipment using Labview
  • Lasers, light sources and optical detectors
  • Optical testing in a laboratory environment
  • Basic electrical skills

As with any employment, proficiency in written and oral skills is a necessity.
Command of Microsoft Office (Power Point, Excel, Access, Word) is also considered essential.
