Mercury Pen-Ray® Lamps

Jelight Mercury Pen-Ray® Lamps are compact, low-pressure mercury ultraviolet light sources designed for analytical, scientific, calibration, and photochemical applications. Their Pen-Ray® design positions the electrodes at one end of the lamp, providing convenient access to confined spaces and allowing the lighted portion of the lamp to be positioned close to samples, detectors, and optical systems. The available models include primarily 254 nm shortwave UV lamps in several lighted lengths, along with a filtered longwave model for applications requiring 365 nm output.

Applications

  • Spectroscopic wavelength calibration
  • Photochemical reactions
  • Photometric and fluorometric instrumentation
  • Chromatography
  • Fluorescence and fluorescent inspection
  • Interferometry
  • Monochromatic UV source applications
  • Analytical and laboratory instrumentation

Features

  • Low-pressure mercury Pen-Ray® lamp design
  • Available with 254 nm shortwave or 365 nm longwave primary output
  • Multiple lighted lengths available for different instrument and application requirements
  • One-ended electrode configuration provides convenient access to confined spaces and optical systems
  • Standard 406.4 mm (16 in.) cord and connector configuration
  • Designed for use with Jelight Pen-Ray® power supplies, with PS-1 or PS-4 compatibility depending on the lamp model
