Light Matters.

Optical Thin Film Design + Optimization Theory + Computational Power


About Us

Light Matters is a design firm that specializes in solving difficult optical film problems, with an emphasis on reducing the thickness and complexity of film stacks without compromising optical performance.

Our patent-pending computational engine and deep theoretical knowledge of the field can help you find solutions not possible with leading software such as OptiLayer and Macleod. Our techniques are effective at finding non-intuitive non-quarterwave solutions to broadband, angle-dependent films with challenging optical and physical constraints.

Solutions

Consulting Services

Film Stack


Light Matters offers fixed-cost consulting services to help you improve your film designs to make them more manufacturable or reduce the overall cost. We work with S&P 500 companies to create significant cost savings by finding solutions that minimize total thickness and complexity without sacrificing optical performance.

Licensing

Film Stack

Our patent-pending computational engine can be easily integrated into your private/public software solutions to speed up your search techniques and enable many other exhaustive search strategies.

Technology

Computational Engine


200M stacks/s


Our patent-pending computational engine can simulate the response of 5 million 64-layer stacks/sec, allowing for massively exhaustive search routines. This allows us to test many more material/thickness combinations than traditionally thought possible.

New Optimization Techniques

Reducing Film Thickness


We have leveraged our compute power by developing new optimization techniques that are more effective at finding solutions than genetic algorithms, particle swarm optimization and many others. We have demonstrated these results in a paper presented at the OSA Optical Interference Coatings conference:

A. Deliwala, "Automated Design of Optical Thin Films via Statistical Inference and Parallelized Computation," in Optical Interference Coatings Conference (OIC) 2019

Merit Function Engineering

Flowchart


Developing the right merit functions for the task at hand is as important as having the right optimization algorithm. At Light Matters we have developed a variety of merit function strategies for the discovery of solutions that meet unique, customer-focused constraints, such as minimizing manufacturing cost, total thickness and number of layers.
