PCT No. PCT/DE83/00138 Sec. 371 Date Mar. 4, 1985 Sec. 102(e) Date Mar. 4, 1985 PCT Filed Aug. 12, 1983 PCT Pub. No. WO85/00927 PCT Pub. Date Feb. 28, 1985.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.
