- Concept development
- Detailed lens design
- Tolerance budget
- Performance analysis, including diffraction effects and tolerance budget influence via Monte-Carlo analysis
- New lens systems automatically fitted to the testplate list of your preferred vendor, to reduce tooling costs
- 2920 stock lens elements from all major vendors in our online catalog, automatically fit into your lens if possible, to save production cost.
- The SYNOPSYS lens design program, written by Mr. Dilworth, can optimize a lens in seconds that would take hours on other programs, using the PSD algorithm. This reduces the time and expense needed to complete your design project.

In 2008, Mr. Dilworth gave a Colloquium talk at the Optical Sciences Center, University of Arizona. This talk was titled
Lens Design, 40 Years On: Where we Were, Where we Are, How we Got There.
This talk gives a concise review of the field of computer-aided lens design for the last 40 or so years.
