Stability is one of the important characteristics of calibrated

light sources. Hamamatsu’s excellent cathode technology

and optimized lamp housing realize high stability and good

repeatability.

sHigh Power

A Xenon lamp emits high intense UV, visible and IR light so

that a reliable measurement can be possible even in the

range of 300 nm to 400 nm, where either a deuterium lamp or

a tungsten lamp doesn’t deliver enough light.
