Good to know – Some facts about arc and halogen lamps

Arc lamps

Features

  • High radiance in the ultraviolet and visible; mercury lamps have spectral lines of very high irradiance in the ultraviolet
  • High ultraviolet output
  • Small concentrated arc
  • Xe lamps have spectral distribution resembling the sun

Benefits

  • Produce highest irradiance on small targets
  • Intense collimated beams due to small, high radiance source
  • Excellent sources for UV photochemistry
  • Can simulate daylight

Halogen lamps

Features

  • High total visible output
  • Excellent stability
  • Excellent photometric or radiometric sources (250 - 2500 nm)
  • Slow variation of output with wavelength

Benefits

  • Easy-to-use
  • Simplify detection in spectral scanning
  • Less expensive than arc lamps
