Torus Spectrometer Delivers High Throughput and Low Stray Light

Date Announced: 10 Mar 2011

Holographic concave grating design elevates Ocean Optics’ newest miniature spectrometer.

Ocean Optics (www.OceanOptics.eu) has launched a family of aberration-corrected holographic 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 (~0.015% at 400 nm) than planar-grating and other miniature spectrometers.

A flat field optical design and a reflective holographic concave grating disperses light; the concavity of the Torus' 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.

Torus is also distinguished by excellent optical resolution (<1. 6 nm FWHM with a 25 µm slit installed in the optical bench) and good thermal stability – wavelength drift is mitigated and peak shape stays the same over a wide temperature range (~0-50º C).

For convenient experiment setups, the Torus Spectrometer interfaces to a computer via its USB port and couples to Ocean Optics accessories. The Torus model is available with a variety of slits, filters and other optical bench accessories for optimising configurations. Free-space optical coupling is accommodated with standard C-mount adapter.

Torus operates via Ocean Optics’ SpectraSuite Spectroscopy Software, which runs in Windows, Macintosh and Linux operating systems, and is compatible with the company’s OmniDriver and SeaBreeze software development platforms. Software is available separately.
