The Q-Sun Xenon xenon (zē`nŏn) [Gr.,=strange], gaseous chemical element; symbol Xe; at. no. 54; at. wt. 131.29; m.p. −111.9°C;; b.p. −107.1°C;; density 5.86 grams per liter at STP; valence usually 0. Test Chamber is offered in several different models to meet testing and budgetary needs. Its xenon arc lamps Xenon arc lamps are an artificial light source. Powered by electricity, they use ionized xenon gas to produce a bright white light that closely mimics natural daylight. Xenon arc lamps can be roughly divided into three categories: Regulation of the degree of saturation (relative humidity) or quantity (absolute humidity) of water vapor in a mixture of air and water vapor. Humidity is commonly mistaken as a quality of air. options are also available. All models of the Q-Sun are equipped with full-spectrum xenon are lamps, the patented Solar Eye irradiance ir·ra·di·ant adj. Sending forth radiant light. [Latin irradi control system to maximize and measure lamp life, a choice of irradiance set points (340 nm or 420 nm), a choice of filters for daylight or window-glass spectra, both chamber air temperature control and black panel temperature control, the patented AutoCal system that allows quick and easy calibration, and a large specimen capacity to accommodate three dimensional parts.
