Abstract: A flash lamp (10), comprising a gas-filled discharge tube (10) made of glass and, at each end, a power electrode (14, 15) that is sealed by means of a glass solder (13), has a glass including one or more of the following U.V. transmission values Tw: at 180 nm: Tw>5%, preferably >9 %; at 200 nm: Tw>30%, preferably >45%; at 254 nm: Tw>60%, preferably >80%. The inside diameter of the discharge tube (11) may be larger than 1.2 times the value of the plasma channel diameter. The starting electrode (16) may be part of the reflector (30-33) or be connected electrically thereto. Flash capacitor (42) may be designed for a charging voltage above 370 volts, preferably above 400 volts.

Abstract: A wall-stabilized infared flash tube has a glass bulb with a flash chamber therein with a cathode lead having an electrode member welded thereto inserted in the flash chamber, the flash chamber, the lead, and the electrode member having dimensions selected for minimizing the influences of white light on the output of the flash tube, so as to enhance the spectrum of the infared output. The flash chamber preferably has a length no longer than 20 mm, and an interior diameter in the range of approximately 0.6 mm to approximately 1.3 mm. A method for manufacturing such a flash tube includes the steps of welding the electrode member to the lead at one location, inserting the lead and electrode combination into a flash chamber of a glass bulb having suitable dimensions, and fusing the lead vacuum-tight to the glass bulb.
