Capabilities

Optical Design

Since 1965 Special Optics has designed and manufactured literally thousands of unique lens systems. Using a combination of internal lens designers and external consultants, we have cataloged base designs ranging from simple bestform lenses and beam expanders to complex image reducers and telecentric scanning lenses. Having a large library of lens designs allows us to meet your design needs without disproportionate design costs. This means that we rarely have to design a system from "scratch." We simply choose a base design, and modify and reoptimize to meet the necessary requirements. In this way the customer need not compromise performance by being forced to choose a standard off-the-shelf lens but, instead, can obtain an exact design without incurring extreme design charges.

Optomechanical Design

In addition to optical design we also supply any necessary optomechanical design. Using state-of-the-art mechanical design software, we insure that our lens systems are both technically feasible and mechanically manufacturable. Our engineering staff works closely with our customers to integrate all mechanical mounting requirements.

We recognize that producing high resolution, diffraction-limited lens systems is often dependent, not only on the optics themselves, but on the quality of the mechanical parts used for assembly.
