NOTE:

①Types 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 due to overheating.

◎ VACUUM FLANGE E3444 SERIES (for L1835)

Since the L1835 vacuum UV deuterium lamp is often used in vacuum chamber, Hamamatsu provides the E3444 series vacuum flanges specially designed for this purpose. Among these, the E3444-02 has a flange conforming to ICF114 specifications, which allows easy installation onto most vacuum chamber ports. The E3444 series also includes "N" flange for a general purpose and flange applied to JIS (Japanese Industrial Standard) specifications. Select the best type depending on the vacuum equipment to be used.
