The E7536 lamp housing was designed to extract the full capabilities of lamps. One example of this is the stationary emission point which ensures high accuracy and easy optical design. The E7536 also delivers high output stability, making it ideally suited for high-precision photometric applications. Light output stability(p-p) is better than 0.3 % Typ. (when used with a Hamamatsu Xenon lamps) or 1.0 % Typ. (when used with a Hamamatsu Mercury-Xenon lamps).
