Main Features


Some of the most popular models are described below with part numbers and further specifications detailed in the table. Custom modifications of these products are available - options include quarts type and size.



90-0012-01 (11SC-1): One of the most popular Pen-Ray Lamps. Its simplicity of physical dimensions lends itself to a multitude of applications. Lamp's lighted length is 2.12" (53.8mm), overall length is 4.62" (117.3mm). Lamp emits Merciry specturm with the primary energy at 254nm. The nomical voltages are 800V (starting) and 270V (operating). Recommended power supply 99-0055-01 (or 99-0055-02).



90-0019-01 (11SC-1L): The longwave version of the 11SC-1. All properties are identical except the quartz tube is sheathed with a blue filter to absorb visible light, increasing the lighted length to 2.25" (57.2mm) and broadening the outside diameter to 0.375" (9.5mm). The principal emission is a 365nm (longwave) by converting the power from 254nm. Power supply 99-0055-01 (or 99-0055-02) is recommended for this lamp.



90-0020-01 (11SC-2): A shorter lighted length (0.75", 19.1mm) version of the 11SC-1 for restricted access. All other properties are identical. Nominal voltages are 800V (starting) and 270V (operating). UVP power supply 99-0055-01 (or 99-0055-02) is recommended to power this lamp.



90-0004-01 (3SC-9): One of the most popular large Pen-Ray Lamp modles with a lighted length of 9.0" (228.6mm) and outside diameter of 0.375" (9.5mm). Lamp is used frequently for photoreactions and ozone production. It emite the Mercury spectrum with primary energy at 254nm. Nomincal voltages are 640V (starting) and 560V (operating). Recommended power supply: 99-0055-01 115V or 99-0004.02 220V.




Specifications


The following tables illustrate the nominal intensities of the standard Pen-Ray Mercury Lamps when current feed into the lamp is a variable. It also includes the typical temperature generated by the lamp at these current. The output is measured at a distance of 0.75" (19.1mm). Emission intensities follow the inverse square law.



All measurements were obtained with a UVX Radiometer for optimum accuracy. There are several other factors that can determine the intensity of a Pen-Ray Lamp besides the current feed. Reflectors and proprietary factors inside of the lamp can contribute to modifications of output intensities.
