These quartz pencil lamps are small, low-pressure, mercury-vapor discharge lamps made of double-bore material with both electrodes at one end. They are very stable lamps and maintain a high output of ultraviolet radiation. They have a spectral emission consisting of many well-separated lines in the ultraviolet and visible portions of the spectrum. They are widely used as spectral calibration sources in spectroscopy, chromatography, and photometry.
Note: A 24" cord set with plug is provided for attachment to the Power Supply. Power supply (#70-298) is not included and sold separately. The UV Light Shields (compatible with #40-759) are sold separately.
