Hamamatsu L10878 consists of a long-life 100 W short arc xenon lamp precisely assembled with a focusing elliptical reflector. The L10878 xenon lamp does not require optical systems and optical axis adjustment mechanisms that are necessary for ordinary xenon lamps. This simplifies equipment design and makes lamp replacement easy and precise since no optical axis adjustment is required.
