For 150 W/200 W
Xenon lamps and Mercury-Xenon lamps
NEW HIGH PRECISION
LAMP HOUSING E7536
The internal cooling fan
ensures safe operation.
ADJUSTABLE OUTPUT LIGHT
The built-in focus lens allows
light flux adjustment.
Stationary emission point
ensures high accuracy.
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 opti-
cal design. The E7536 also delivers high output stability,
making it ideally suited for high-precision photometric appli-
cations. 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).
qHigh output intensity and collimated light flux
A reflective mirror and focus lens are incorporated. The mir-
ror collects light from a lamp very efficiently to obtain a high
output of over 1.5 times. The focus lens can be used to pro-
vide collimated light output.
qBuilt-in starter for improved lamp start-up operation
The built-in starter prevents high-voltage leakage, thus
improving start-up operation of the lamp and also minimiz-
ing noise which might otherwise occur at lamp start-up.
HIGH OUTPUT INTENSITY
Built-in reflective mirror
EASY OPTICAL AXIS
A starter is incorporated.
qAdjustable light flux
The focus lens can be moved back and forth by turning the
screw on the front flange (with the accessory tool), to adjust
the output light flux. The desired light flux can be easily
obtained to match your specific application.
qEasy optical axis adjustment during lamp replacement
The optical axis can be easily adjusted by using the acces-
sory tool, without removing any lamp housing covers. Three
adjustment screws are provided in easy-to-access posi-
tions: one on the side of the housing (for right-left move-
ment of the lamp), one at the upper part on the rear (for ver-
tical movement of the lamp), and one in the center on the
rear (for back and forth movement of the mirror).
If the side cover becomes loose or the temperature in the
lamp housing rises to an abnormal level, the interlock
function triggers automatically to stop lamp operation.
The built-in cooling fan maintains the surface temperature of
the lamp housing to a safe level below +40 °C.
