The USB4000 Miniature Fiber Optic Spectrometer from Ocean Optics is a low-cost, high-performance system easily configured for thousands of UV-VIS-Shortwave NIR applications from 200-1100 nm. Flexible fiber optic spectroscopy lets you bring the instrument to the sample.

Modular system can be optimized to fit your application needs

The USB4000 features a high-sensitivity linear CCD array that provides unusually high response and excellent optical resolution in a miniature package -- for a fraction of the cost of larger, less-flexible systems.

The USB4000 is part of a modular spectrometer system -- users select from 3 detectors, 14 gratings, 6 slits and hundreds of fiber optic accessories such as light sources, probes and optical fibers -- to configure small-footprint, application-specific systems for absorbance, reflectance and emission. The USB4000 plugs directly into any computer and has an onboard A/D convereter to ensure a hassle-free instrument-to-PC interface. This remarkable flexibility makes the USB4000 equally attractive to researchers, new product developers and OEM integrators.

The USB4000 Spectrometer is just one part of a fully integrated spectrophotometric solution to your optical-sensing challenges. That's where our applications scientists come in -- by helping you select the components that will become the optimum system for your application. Not only have we sold more than 75,000 spectrometers, we've enabled thousands of applications -- systems for everything from cancer detection to color measurement, plasma monitoring to particle size analysis.

The USB4000 features a familiar optical design -- the crossed Czerny-Turner -- that has been reconfigured for an optical bench small enough to fit into the palm of your hand. This compact optical bench -- with no moving parts -- has a high-sensitivity 2048-element linear CCD-array detector that accepts light energy transmitted through single-strand optical fiber and disperses it via a fixed grating across the array. Despite its tiny size, the bench delivers low stray light and high resolution, comparable to conventional 1/4-meter monochromators.

Ocean Optics miniature fiber optic spectrometers offer high performance at low cost, in a convenient, modular package. Operating performance will vary according to a number of factors, including spectrometer configuration -- especially the groove density of the grating and the size of the entrance optics -- as well as the application itself (for example, low vs. high light level applications).
