Pen-Ray Physical and Electrical Properties

Pen-Ray Lamps are low pressure, cold cathode UV lamps made of double bore quartz tubing. This design allows the electrodes to be positioned at one end of the lamp providing easy access into small apertures. Depending on the lamp characteristics, primarily the lighted length, the power requirement to the lamp can range from 2 to 20 watts and produce from 40 uW/cm2 to over 20 mW/cm2.

   Major advantages of Pen-Ray
   Lamps include:
Isolated spectral lines for calibration purposes
Slower solarization of the quartz tubing
Contamination free internal environment for superior quality and life of the lamp
Increased stability of the emission for accuracy and reproducibility
Long life: 5,000-8,000+ hours depending on use
Miniature lamp size: As small as 1.85"(47mm) with a lighted length of approximately 0.04" ((1.02mm)
Cool burning compared to higher pressure lamps
Variable energy output option based on current and components
