Abstract
An improved light beam combiner is disclosed that creates a more uniform light source across the UV, Visual, and NIR range. It is an optical mechanical device made up of a standard high low dielectric thin film which, when placed at a 45 degree angle between a Deuterium lamp and a Halogen or Tungsten lamp, reflects the UV portion of a Deuterium lamp and passes the visual portion while also allowing the visual energy of a Halogen or Tungsten lamp to pass resulting in a more uniform light source for use in spectroscopy.
