            Moor Instruments, established in 1987, is a world leader in
            the design, manufacture and distribution of laser Doppler
            systems, used for the monitoring and imaging of blood
            fl ow in the microvasculature.
            First hand experience of laser Doppler research and
            development within Moor dates back to 1978 and with
            this we have the breadth of knowledge to help with your
