Xenon light sources offer the highest flux density short of a laser and are commonly used in applications requiring high brightness in the ultraviolet, visible and near infrared ranges.

One of the best sources of high brightness UV (220nm) to very near infrared (ca.900nm) light is a Xenon short arc lamp. High pressure Xenon lamps produce a continuum emission spectrum with some fine structure superimposed. This optical output can extend well into the infrared region with high flux densities

The spectral output closely resembles that of the solar spectrum because most Xenon arc lamps have arc temperatures around 6000K and as such make ideal solar simulators. At Camlin Photonics, we have both pulsed and continuous Xenon lamps available.


Our APOLLO X-SERIES Xenon light sources provide the ideal solution where very high luminance (point light source) is required. Our range provides options of output bulb power of 75W, 150W, and 450W. These lamps are used as optical sources in a wide range of applications and demonstrate long bulb lifetimes.

Our unique lamp housing ensures correct cooling of the bulb, is warm (and safe!) to touch, and ensures highly stable operation over long periods of time. Each lamp housing uses a XYZ placement of the bulb for optimum alignment as well as a rear reflector that improves light collection by at least 30%. The lamp housing comes with fused silica condenser optics that can be set to produce collimated or focused output. Multiple safety interlock and thermal sensors ensure fully safe operation. Simply speaking, the lamp bulb cannot be struck with the cover open nor operate in an over-temperature regime.


Our APOLLO Xp pulsed xenon light source has all the benefits of a continuous xenon source but instead provides a short high intensity light pulse of a few microseconds and is ideally suited for time-resolved measurements. As with our continuous sources, our pulsed sources are supplied complete with housing, high performance focussing optics, and stabilised power supply.
