High Intensity Light Source HIS 13
The VUV source HIS 13 is a windowless gas discharge light source for the
production of VUV light under vacuum conditions. It can be operated with various discharge gases, such as helium, neon, argon, krypton, xenon or hydrogen. The
operation of the lamp is based on the principle of a cold cathode capillary discharge. There is a windowless direct sight connection between the discharge
area and the target. The discharge current is electronically stabilised. The lamp is water cooled in order to allow for high discharge currents (up to 300 mA) and to
reduce electrode degradation resulting in prolonged service intervals. No outer part of the lamp is on high voltage, thus no shielding cage is needed. An integral
portaligner faciliates the positioning of the light spot on the sample in a range of ± 3°.
