Abstract
A spectral filter and mounting assembly comprising a flat quartz disk with coatings to control the light spectrum, a heat transfer adapter, a split-ring retainer for use in a drop-in arc lamp assembly that includes an arc lamp with fitted cathode and anode heat sinks each including a thin-wall copper strip that is brazed in pleated folds between inner and outer cylindrical rings to create cooling fins. The drop-in lamp assembly also includes an insulative sleeve in which the arc lamp and heat sinks are disposed and a pair of connection bushings piercing the wall of the sleeve and providing an electrical connection to the arc lamp outside the sleeve. The arc lamp includes a copper heat conduction flange that surrounds a front window reduced in diameter from the diameter of the arc lamp. The flange conducts heat generated in the window and the spectral filter during operation directly to the cathode heat sink. Both heat sinks are forced-air cooled by the fan, thus cooling the window and the spectral filter.
