Robust Electronics
OneFocus Advantage
The USB4000 is a modular spectrometer. You can select a model that is preconfigured
for a particular application or you can build your own. Our Application Sales Engineers
help you with selection of grating, slits and optical bench accessories, as well as
sampling accessories such as fibers, light sources and cuvette holders.
Features
• Reliable, robust spectrometer with good signal-to-noise performance
• Great response across the 200-1100 nm wavelength range
• Hundreds of configurations possible with modular design
• Built-to-suit wavelength range and optical resolution performance
• Triggering functions for synchronization between the spectrometer and other devices
The USB4000 Spectrometer is distinguished by its enhanced electronics: 16-bit A/D
resolution with auto nulling feature (an enhanced electrical dark-signal correction);
EEPROM storage of calibration coefficients for simple spectrometer start-up; 8
programmable GPIO signals for controlling peripheral devices; and an electronic
shutter for spectrometer integration times as fast as 3.8 milliseconds -- a handy feature
to prevent detector saturation.
Chlorophyll in water is measured with a USB4000 configured for fluorescence.
A 450 nm LED was used for excitation and a cuvette holder for the sample.
