Torus Spectrometer Delivers High Throughput And Low Stray Light

Concave grating design elevates Ocean Optics' newest miniature spectrometer

Ocean Optics has launched a family of aberration-corrected concave diffraction grating spectrometers that delivers low stray light, high throughput and excellent thermal stability for applications ranging from absorbance measurements of optically dense solutions to fluorescence measurements in solutions and powders. Torus is a compact Visible spectrometer (360-825 nm) with greater throughput and less stray light (~0.03% at 400 nm) than most other miniature spectrometers.

Torus has a clever flat field optical design and uses a reflective concave grating to disperse light; the concavity of the grating reflects and focuses the light and the grating groove pattern disperses the light. The toroidal nature of the grating further enhances the aberration correction and efficiency.

The Torus Spectrometer interfaces to a computer via its USB port and couples to Ocean Optics accessories for convenient experiment setups. The Torus model is available with a variety of slits, filters and other optical bench accessories for optimizing configurations. It operates via Ocean Optics' SpectraSuite Spectroscopy Software, which runs in Windows, Macintosh and Linux operating systems.
