USB4000 Miniature Fiber Optic Spectrometer

We’ve sold over 130,000 spectrometer channels for thousands of applications, and we've used that experience to make the most flexible, versatile and cost-effective spectrometer ever built. The USB4000 is our next-generation flagship spectrometer, with a 3648-element Toshiba linear CCD array for increased signal-to-noise and enhanced electronics for controlling the spectrometer and accessories. The USB4000 starts at $2540. The USB4000 is made-to-order per your optical bench selections -- including order-sorting filters and entrance slits sizes -- which are available as separate line items.

Pre-configured USB4000-UV-VIS & USB4000-VIS-NIR are in-stock and ready to ship!

World’s Most Popular Spectrometer Just Got Better

We redesigned the USB2000 -- the most popular spectrometer in the world -- to include an advanced detector and powerful high-speed electronics. The USB4000 features a 16-bit A/D, four triggering options, a dark-level correction during temperature changes, and a 22-pin connector with eight user-programmable GPIOs. What’s more, the USB4000 interfaces to computers with Linux, Mac or Windows operating systems. The modular USB4000 is responsive from 200-1100 nm and can be configured with various Ocean Optics optical bench accessories, light sources and sampling optics to create application-specific systems for thousands of absorbance, reflection and emission applications.

Electronic Advancements

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 (for faster integration times using the External Hardware Trigger Mode, see our USB2000+ Spectrometer). In addition, the USB4000 has signal-to-noise of 300:1 and optical resolution (FWHM) ranging from 0.3-10.0 nm (depending on your grating and entrance aperture selection).

Streamlined Start-up Software & Hot Swapping

The USB4000 interfaces to a computer via USB 2.0 or RS-232 serial port. Data unique to each spectrometer is programmed into a memory chip on the USB4000; SpectraSuite Spectroscopy Operating Software reads these values for easy setup and hot swapping among computers, whether they run on Linux, Mac or Windows operating systems. When connected to a computer via USB, the USB4000 draws its power from the computer. With its small-footprint design, plug-and-play convenience, advanced electronics and powerful detector, the USB4000 has succeed the USB2000 as the most frequently specified fiber optic spectrometer in the world.

Optical Bench Options

At Ocean Optics, we understand that your work is unique and that you want a spectrometer to fit your specific needs. What makes the USB4000 Spectrometer so special are the options that allow you to configure the bench for your application. Choose USB4000 Optical Bench Options such as entrance aperture size, detector accessories, filters a grating and more. Our application scientists will help you determine which configuration will best work for you.

We also have a limited-time upgrade offer designed especially to enhance your UV sensing and boost UV response by over 20%. The upgrade is available for Gratings 1, 5, 7 and 10.

Detector Options

The USB4000 uses the Toshiba TCD1304AP 3648-element linear CCD-array detector. To properly configure a USB4000 Spectrometer for your application, you'll need to specify one of the Four Detector Options offered; all four options include the Toshiba detector but with different coatings and windows. Your application scientist can help you determine which detector options will best work for you.

Installation and Operation Manual

Sampling Accessories

When you purchase a USB4000, you can also choose from Ocean Optics' complete line of spectroscopic accessories.  Most accessories have SMA 905 connectors for application flexibility. Changing the sampling system is as easy as unscrewing a connector and adding new components or accessories, such as USB4000 direct-attach accessories, and additional light sources, sampling holders, filter holders, flow cells, fiber optic probes and sensors, collimating lenses, attenuators, diffuse reflectance standards, integrating spheres and our extensive line of optical fibers.

Pricing

* Pre-configured, off-the-shelf USB4000 Spectrometers (such as the USB4000-UV-VIS, USB4000-VIS-NIR and USB4000-FL) have the detector and other bench components built-in.

Specifications

Serial port operation tips: When using the serial port, the USB4000 requires a single 5-volt power supply (not included). Also, SpectraSuite Spectroscopy Software does not support spectrometer operation via the serial port. However, using the included Serial Port Command Set, you can write your own software that makes serial port operation possible.
