THL系列光源采用100W灯泡（6001）作为照明光源，比孤光灯更稳定，且不会发出强紫外光和臭氧，平滑的曲线输出，更适合光谱应用。

The Light Source THL100 uses the 6001 100 W TH lamp as its illumination source. This Tungsten Halogen lamp exhibit better output stability than arc lamps and do not produce strong UV light emission or toxic ozone. Their smooth spectral output curve make them useful for radiometric and photometric applications.

光学开关：

光学开关用于关闭光路，不需要光照时保护使用人员免受紫外线辐射，比如：预热光源、安装光学元件，无需频繁开关光源。

Manual Shutter：

A manual shutter is integrated into the THL100 to allow the user to close off the light path, blocking any light output from the system. This allows the user to be protected from UV radiation when light output is not required, such as warming up the lamp while preparing a setup or making a minor change in setup, without frequent and unnecessary restarts of the lamp.

六档滤光片轮：

六档滤光片轮，可以安装1-6个不同滤光片，直径25.4mm（1英寸）,便于滤光片。

Integrated Six Position Filter Wheel：

A filter wheel is integrated into the assembly of the THL100. Up to six order-sorting or neutral density filters can added (1.0 in or 25.4 mm diameter, 0.2 in. or 6 mm thickness) and filters can be changed.
