商品货号:ECS001276
商品品牌:ocean optics
详细介绍

红潮光谱仪是一个低费用、小型化的实验室用光谱仪。USB650-VIS-NIR红潮光谱仪的波长范围为350~1000nm,由于配置了25 μm的入射光狭缝,红潮光谱仪可以提供约2.0nm的光学分辨率(FWHM)。USB650-VIS-NIR光谱仪预配置USB-ISS-VIS LED卤灯光源和样品池,该样品池1cm见方,可用于吸光度测量。

特点

  • 集成度高,光谱范围为350-1000nm,2.0nm光谱分辩率(FWHM)
  • 吸光度测量灵敏度为0.1
  • 可直接连接海洋光学的氘灯和样品池
  • USB2.0接口

 

Direct-attach Light Source

The USB650-VIS-NIR uses the USB-ISS-VIS combination sample holder (1-cm cuvette)and violet LED-boosted tungsten light source for measuring relative absorbance。 The light source boosts signal in the blue and provides over 45,000 hours of use 

 

Modular Design

Ocean Optics offers complete line of fiber optic sampling accessories and teaching tools to further enhance your USB650-VIS-NIR system。Most accessories have SMA905 connectors for application flexibility; changing the sampling system is as easy as unscrewing a connector and adding new components or accessories。

For even more flexibility,consider the CHEM4-VIS-FIBER. An optical fiber based system, the CHEM4-UV-FIBER leets you quickly and easily couple fiber optic accessories,such as reflection probes or transmission dip probes,to the system's light source. 

Plug-and -play Operation

The USB650-VIS-NIR interfaces to a PC, PLC or other embedded controllers via a USB 2.0 PORT. Date unique to each spectrometer is programmed into a memory chip on the USB4000; our spectrometer operating software reads these values for easy setup and hot swapping among PCs.
