These sources run 50 to 250 W quartz tungsten halogen lamps. The output is a smooth VIS-NIR continuum, useful for radiometry. We offer several families of low wattage QTH Sources; this family is our fully featured Research Series. Choose one of these systems if you need to interchange lamps or have a stability critical application requiring the 68950 Light Intensity Control System.
