Welcome

Thank you for your interest in MJC Optical Technology.

MJC Optical Technology, established in 1991, specializes in design and development of custom optics-based and fiber-optics-based sensors and test systems and in development of custom technical and scientific software. Our contribution to the success of a client's project can include evaluation and numerical modeling of sensing technologies, integration of sensors into a client's instrumentation, development of custom sensors and test systems, as well as development of custom software.

We offer a comprehensive skill mix and experience at all stages of design and development of optical sensor systems, and custom software, as well as a flexible range of services. Please visit the Services and Expertise pages for more detail.

Please also visit the Publications page for technical notes and tutorials, as well as the Products page for a list of our data processing software.
