S2000 Miniature Fiber Optic Spectrometer

The S2000 Miniature Fiber Optic Spectrometer from Ocean Optics was a low-cost, high-performance spectrometer easily configured for thousands of UV-VIS-Shortwave NIR applications from 200-1100 nm. The S2000 featured a high-sensitivity linear CCD array that provided unusually high response and excellent optical resolution in a miniature package.

The S2000, once our flagship product, is no longer available. Configuring the S2000 to work with external analog-to-digital converters could sometimes be time consuming and complicated. Several years ago we introduced USB-series spectrometers and the S2000 ceased to be the most popular spectrometer choice.

Miniature Optical Design

The S2000 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.
