Fiberlight lamp - 光纖燈

詳細介紹

Fiberlight lamp - 光纖燈

光纖燈是一種緊湊型光源，光譜范圍為紫外線和可視光譜范圍（從200nm到1100nm）。光纖燈的核心為無電頻觸發(fā)氘燈或線型光源。

這一微型燈可為電池驅動的便攜式儀器提供紫外線光譜。

光纖燈產(chǎn)生的全部是紫外線/可見光源。

它由一個燈模塊（透光型排列的氘燈和鎢燈或線性輻射器），窗口和 SMA 光纖接口組成。

另外還有不帶直接接入測量單元的光纖接口型供選擇。所有部件固定在電路板上，由外部 TTL 信號進行控制。光纖燈可用一個12Vdc/0.6A 的電源驅動，特別適用于無電網(wǎng)供電的便攜式分光計。

Data Sheet FiberLight

The miniature UV/vis light source for 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.

Key features of Heraeus FiberLight:

RF induced deuterium and visible light source

Electrodeless lamp, instant switch on/ switch off

Exchangeable lamp modules for differentUV/vis or line spectra

Ready to use -whole unit mounted oncompact circuit board

Very small size
