With its smooth spectral curve and stable output, the 6319 Quartz Tungsten Halogen (QTH) Lamp is a popular visible and near infrared light source. This lamp uses a dense rectangular filament, producing high image brightness. It does not exhibit the sharp spectral peaks characteristic of arc lamps and emits little UV radiation. A doped tungsten filament is positioned inside a quartz envelope. The envelope is filled with rare gas and a small amount of halogen. Current flowing through the filament heats the tungsten, the white light produced radiates through the clear envelope. This model has an average operational lifetime of 100 hours (with a longer expected lifetime if operated at lower compliance voltages).
