Programmable microcontroller
CHEMOSB4-VIS-NIR fiber optic spectrometerUse ourUSB4000 a spectrometer.USB4000The spectrometer comes with a programmable microcontroller, which can easily control the spectrometer and its accessories. Through a 22 pin connector, you can perform all operational parameters in the software: control the light source, create processes, and obtain information from external devices. The microcontroller has 8 programmable digital input/output interfaces for exchanging data with external devices (contact our engineering and technical personnel for relevant information to write GPOs programs). )
Standard component design
Ocean Optics provides a complete set of fiber optic sample accessories and teaching tools to enhance your CHEMOSB4-UV-VIS system. Most accessories come with SMA905 connectors for various applications; Changing the sample system is also very simple, just remove the connector and add new components and accessories.
To gain more flexibility, consider purchasingCHEM4-UV-FIBERtypefiber spectrometer.CHEM4-UV-FIBERfiber spectrometerIt is a fiber optic system that allows you to quickly and easily connect light sources to fiber optic accessories such as reflective probes or transmissive immersion probes.
Plug and play operation
CHEMOSB4-VIS-NIR fiber optic spectrometerpass throughUSB2.0perhapsRS232The serial interface can be connected to computers, handheld computers, or other built-in controllers. When using a serial port, it is necessary to provide the system with5Volt power supply (not included). The proprietary parameter data of each spectrometer is written in the memory on USB4000; Our spectrometer operating software reads these values for parameter adjustment and heat exchange between computers.
Serial Port Operation TipsWhen using a serial port, it is necessary to provideUSB4000System provided5External power supply for volts (not included).SpectraSuiteThe spectrometer software does not support spectrometer operation through serial ports. However, with the built-in serial port command settings, you can write your own software program that can be used for serial port operations.
