The 6335 Quartz Tungsten Halogen (QTH) is a special, long lifetime type QTH lamp. Whereas QTH lamps typically have an operating lifetime on the order of tens of hours, the 6335 has a typical lifetime of 300 hours. This 250 W QTH lamp emits minimal ultraviolet light emission and high intensity visible and infrared light emission, without the typical spectral peaks of an arc lamp. This smooth spectral output makes QTH lamps the preferred choice for spectroscopy applications such as spectral sensitivity characterization of photoconductive and photovoltaic materials.

6335石英钨卤素(QTH)是一种特殊的长寿命QTH灯。QTH灯具的使用寿命通常是几十小时,而6335灯具的使用寿命通常是300小时。这款250w QTH灯发出的紫外光和高强度的可见光和红外光,没有典型的弧光灯的光谱峰值。这种平滑的光谱输出使得QTH灯成为光导材料和光电材料光谱灵敏度表征等光谱应用的首选。
