产品描述

CHEMUSB4-UV-VIS分光光度计是我们研发的USB接口光谱仪技术与标准附件的完美结合。这套系统由下列组件构成：结合了USB4000光谱仪，氘钨卤光源，1cm的比色皿支架以及高速电子采样部件。 

CHEMUSB4-UV-VIS分光光度计覆盖了210-880nm光谱范围，光学分辨率为1.0nm(FWHM)，能在1秒内获取3648象素的波长光谱。

 

产品特点：

  • 全集成的预装系统，覆盖210-880 nm光谱范围，光学分辨率为1.0nm(FWHM)。
  • 小型化系统，是实验室和教学的理想选择。
  • 直接连接有氘钨卤光源与样品支架。
  • 吸光率小至0.01
  • 通过USB2.0接口可快速将光谱仪与计算机相连。

 

Direct-attach Light Source
The CHEMUSB4-UV-VIS features the USB-ISS-UV-VIS combination sample holder and deuterium tungsten light source (200-1100 nm). This sampling system holds standard 1-cm cuvettes for easy-to-perform absorbance measurements. The USB-ISS-UV-VIS allows you to control both the intensity of the tungsten bulb and the shutter via software. The USB-ISS-UV-VIS requires an external power supply (included).
 
Programmable Microcontroller
The CHEMUSB4-UV-VIS uses our USB4000 Spectrometer. The USB4000 features an onboard programmable microcontroller that provides you with considerable flexibility in controlling the spectrometer and accessories. Through a 22-pin connector, you can implement all operating parameters in the software: control light sources, create processes, and retrieve information on external objects. You have access to 8 user-programmable digital Inputs/Outputs for interfacing to other equipment.
 
Modular Design
Ocean Optics offers complete line of fiber optic sampling accessories and teaching tools to further enhance your CHEMUSB4-UV-VIS system. Most accessories have SMA 905 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-UV-FIBER. An optical fiber based system, the CHEM4-UV-FIBER lets 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 CHEMUSB4-UV-VIS interfaces to a PC, PLC or other embedded controllers via USB 2.0 or RS-232 serial port. When using the serial port, the system requires a single 5-volt power supply (not included). Data 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.
 
Serial port operation tips: When using the serial port, the USB4000 requires a single 5-volt power supply (not included). Also, SpectraSuite Spectroscopy Software does not support spectrometer operation via the serial port. However, using the included Serial Port Command Set, you can write your own software that makes serial port operation possible.
