Diffraction Ltd


Diffraction Limited was founded in 1993 by Douglas George. Diffraction Limited develops and manufactures a wide range of scientific imaging systems and tools, including low-light imaging cameras, filter wheels, adaptive optics systems, control and processing software, and observatory control and protection systems. In 2014 Diffraction Limited acquired the assets of SBIG, which has manufactured CCD imaging systems since 1989.  All engineering and manufacturing is now done at the company’s custom-built facility in Ottawa, Ontario.


Diffraction Limited and SBIG are pioneering organizations in the field of astronomical imaging hardware and software, which have now joined forces to design and manufacture the best scientific imaging products available today.


Our philosophy is to be constantly learning and innovating, and to listen to our customers.
