Fiberlight lamp - 光纤灯

 

光纤灯是一种紧凑型光源,光谱范围为紫外线和可视光谱范围(从200nm到1100nm)。 光纤灯的核心为无电极高频触发氘灯或线型光源。
 
这一微型灯可为电池驱动的便携式仪器提供紫外线光谱。
 
光纤灯产生的全部是紫外线/可见光源。
它由一个灯模块(透光型排列的氘灯和钨灯或线性辐射器),窗口和 SMA 光纤接口组成。
另外还有不带直接接入测量单元的光纤接口型供选择。 所有部件固定在电路板上,由外部 TTL 信号进行控制。 光纤灯可用一个12Vdc/0.6A 的电源驱动,特别适用于无电网供电的便携式分光计。

 Data Sheet FiberLight

The miniature UV/vis light source for mobile spectroscopy and on-line process analysis
 
FiberLight is a very compact light source for the ultraviolet, visible and near infrared spectral range (from 200 nm to 1100 nm). The heart of FiberLight is an electrode-less RF induced deuterium lamp or line source.
 
The miniature lamp opens up UV spectroscopy to portable, battery operated instruments. Application examples are organic chemistry, pharmaceuticals, petrochemicals, agriculture, the environment and life science for on-site analyses and diagnosis. Another area of applications is in small instruments for on-line process analysis.
 
FiberLight is a complete UV/vis light source. It consists of the lamp unit, with deuterium and tungsten lamps in shine-through array, shutter and optical coupling with SMA fiber optic connection. There is also an optional version without optical fiber connector for direct illumination of the measurement cell. All elements are mounted on a circuit board and are externally controlled through TTL signals. FiberLight can be operated with a 12Vdc/0.6A power supply.
