With Enhanced ElectronicsJune 12, 2006 -- The USB4000, a 3648-element CCD-array miniature fiber optic spectrometer, replaces Ocean Optics’ USB2000 spectrometer.
modular USB4000 features enhanced resolution and onboard electronics
for convenient integration of spectrometer operation and for additional
functions such as light-source control and external device
triggering. It is responsive from 200-1100 nm and can be
configured with various Ocean Optics optical bench accessories, light
sources and sampling optics to create systems for thousands of
absorbance, reflection and emission applications.
USB4000 is distinguished by its enhanced electronics: 16-bit A/D
resolution for auto nulling (an enhanced electrical dark-signal
correction), EEPROM storage of calibration coefficients for simple
spectrometer startup, eight programmable GPIO signals for controlling
peripheral devices, and an electronic shutter for spectrometer
integration times as fast as 10 microseconds, which prevents detector
saturation. In addition, the USB4000 has signal-to-noise of 300:1,
sensitivity of 130 photons/count at 400 nm and optical resolution
(FWHM) ranging from 0.3 to 10.0 nm.
The spectrometer interfaces
to PCs, PLCs or other embedded controllers via a USB 2.0 or RS-232
serial port. Operated via the serial port, the USB4000 requires a
single 5-volt power supply. Data unique to each spectrometer is
programmed into a memory chip on the USB4000; Ocean Optics spectrometer
operating software reads these values for easy setup and hot-swapping
