These are inexpensive sources of high brightness, VIS radiation. The output is a focused spot ~10 mm in diameter. These sources are widely used for illumination of large core fiber bundles and liquid light guides. Because the spot size is so large, these are not the most efficient fiber illuminators, and are not usable with small core fibers, but they are economical and simple. The lamps are 12 V quartz tungsten halogen lamps with a dichroic reflector surrounding the lamp envelope. The reflector collects the lamp radiation and produces a high intensity spot in front of the reflector (see Fig. 2). We offer two lamp types, differing in spectral output and output power.
