Technical specifications and features of the Ocean Optics USB4000 spectrometer.
The USB4000 is a compact, solid‑state spectrometer that uses a 16‑bit A/D converter, a Toshiba TCD1304AP 3648‑element CCD detector, and offers a wavelength range from 200 nm to 1100 nm. It can be powered from the USB +5 V supply or an external source and communicates via USB 2.0 or RS‑232.
The device provides up to six programmable GPIO pins, multiple trigger modes, and a variety of optics options. Detailed mechanical dimensions, electrical pinout, and software command examples are included for integration into OEM systems.
