FEATURES
sHigh
Stability
Stability is one of the important characteristics of calibrated
light sources. Hamamatsu鈥檚 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鈥檛 deliver enough light.
