Upgrade for fibre optic spectrometer

Ocean Optics has launched its next-generation miniature fibre optic spectrometer. The USB4000 replaces the company's USB2000, one of the most successful miniature fibre optic spectrometers in the world. Small enough to be held in the palm of a hand, it features a 3648 element linear CCD array for substantially increased signal-to-noise and enhanced 16bit electronics for controlling the spectrometer and accessories.

With a choice of 14 gratings and six slits, the USB4000 can be configured for thousands of absorbance, reflection and emission applications.

It features five triggering options, is responsive from 200 to 1100nm and has an integration time as short as 10us, enabling the measurement of transient events such as laser pulses.

The USB4000's onboard, programmable microcontroller provides considerable flexibility in controlling the spectrometer and accessories.

A 22-pin connector enables integration of all operating parameters in the software and additional functions such as light source control and external device triggering.

There are eight user-programmable digital I/Os for controlling peripheral devices.

A choice of hundreds of fibre optic accessories such as light sources, probes and optical fibres allow creation of the optimal system for almost any application.

The USB4000 interfaces to a PC, PLC or other embedded controller via USB 2.0 or RS232 serial port.

Data unique to each spectrometer are programmed into a memory chip which Ocean Optics' SpectraSuite software reads for simple setup and hot swapping among PCs.
