USB650-UV-VIS Spectrophotometer for Education
商品货号:ECS001275
商品品牌:ocean optics
详细介绍

红潮光谱仪是一个费用低、体积小的实验室用光谱仪。是低预算的教学与研究实验室常规设备的理想选择。USB650-UV-VIS红潮光谱仪的波长范围为200~850nm,配有650有效像素的检测器,可以在全光谱上显示650个数据点,或在每1nm上显示一个数据点。由于配置了25μm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)。

 

直连光源

USB650-UV-VIS光谱仪可直连USB-ISS-UV-VIS氘卤灯光源和样品池,光谱范围为200-850nm。该样品池1cm见方,可用于吸光度测量。USB650-UV-VIS光谱仪可通过软件来控制光强和开关。

 

模块化设计

海洋光学提供完整的光纤及附件产品,可简单地通过SMA905接口和光谱仪连接,极大地增强了USB650-UV-VIS光谱仪的应用领域,其中CHEM4-UV-FIBER光纤光谱仪可使用户方便地连接各种附件,如反射探头和透射探头等。

 

即插即用

众购彩票网站USB650-UV-VIS通过USB2。0和电脑相连,可以非常迅速地传输数据。
