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.

6319石英钨卤素灯(QTH)光谱曲线平滑，输出稳定，是一种常用的可见近红外光源。这种灯使用密集的矩形灯丝，产生高的图像亮度。它不表现出弧灯的尖锐光谱峰特征，发射出的紫外辐射很少。掺杂钨丝被放置在石英外壳内。外壳充满稀有气体和少量卤素。流过灯丝的电流加热钨;产生的白光通过透明的外壳辐射出来。
