High Intensity, 150 W Type, Vacuum UV (from 115 nm) Light Source The L1314 and L1835 are water-cooled 150 W deuterium lamps that deliver a radiant intensity 3 to 4 times higher than standard 30 W deu- terium lamps. The lamp bulb is enclosed in a cylindrical metal jacket specially designed for water cooling. The L1314 has a synthetic silica window for an efficient emission of UV radiation, and the L1835 has a MgF2 (magnesium fluoride) window which even allows emitting va- cuum UV radiation. Select the lamp that matches wavelengths re- quired by your application. Vacuum flanges are also available as op- tions in the L1835 for easy mounting to a vacuum chamber. •Spectrophotometer, Fluorescence Spectrophotometer •Removal of static electricity from the semiconductor wafer, flat panel display and so on •PID (Photo Ionization Detector) •Solar Simulator •Photochemical Reaction •Light Source for Excitation RECOMMENDED OPERATING CONDITION / CHARACTERISTICS (at 25 °C) NOTE: ©Types L1314 and L1835 cannot be operated without cooling water passing through them. Please make sure that the lamp is positioned properly so that the two nozzles are aligned vertically, with the water flowing into the jacket from the bottom nozzle and leaving from the top nozzle. If this arrangement is not observed, the lamp might be damaged Flow of cooling water Figure 1: Spectral Distribution ^Subject to local technical requirements and regulations, availability of products included in this promotional material may vary.
