系统简介:
System Description
Filmonitor BS是一个多波长光谱仪系统,其中包括了长寿命电压卤钨光源、线阵CCD探测器、嵌入式计算计以及相应的数据采集、计算软件。光缆联接的光路保证了系统的柔和性以及高信噪比和长时间工作稳定性。线阵CCD使得全光谱范围内每个波长处的信号都能够同时采集,并在恶劣的光学环境及采集到较低的信号。
The Filmonitor BS is a multi-wavelength spectrophotometer comprised of a long life, low voltage halogen light source, Linear CCD detector, embedded computer and software with sophisticated algorithms integrated into an easy to use instrument. State of the art fiber optic components deliver high signal to noise ratio and long-term stability. The Linear CCD allows the entire range of individual wavelengths in the spectrum to be detected simultaneously and is especially suitable for resolving low level signals in a noisy environment.
系统可以配置为透射模式或者反射模式。
System can be configured to be used in Transmittance Mode or Reflectance Mode.
