​​​​​​​​Pulse Photonics has over 35 years’ experience in the research and development of scientific lighting and imaging solutions. We market our own range of high power, short duration flash lighting units for use in conjunction with scientific and industrial cameras. We also work on bespoke projects for clients in the aerospace, military/defence, academic and industrial sectors.  Our electro-optic expertise enables us to take their concepts through all stages of design and development from prototyping through to in-house manufacture.

We specialize in a diverse range of lighting solution from fast pulsing LEDs used in microscopic particle flow analysis to high speed / high intensity discharge flash lighting used in hypervelocity free-flight studies.  Along with our standard lighting solutions we can build point-source or area illumination units to meet our clients' specific applications.

Pulse Photonics has an extensive skillset in designing non-standard line-scan CCD & CMOS digital camera for use in machine vision, as well as interface systems to integrate them.
In addition to custom-built cameras we construct optical systems such as Schlieren imaging rigs. These are used with a light source and camera to visualize density variations in transparent media.
