    The Torus Miniature Spectrometer from Ocean Optics is a Visible range (360-825 nm) unit that delivers low stray light (0.015% at 400 nm) and high throughput.

    Torus delivers scientific-grade performance with outstanding thermal stability, making is a brilliant choice for color measurement of LEDs and a wide range of other challenging applications.

    For Torus, we use a variable line spacing grating with 550 (+/-2) grooves/mm groove density at center and a nominal blaze wavelength of 400 nm. This design yields an optical bench in which light can be manipulated more efficiently.

    The concave grating also helps to improve thermal stability of the Torus. Wavelength drift is nearly eliminated and peak shape stays the same over a wide temperature range. As a result, Torus makes possible precision metrology, fluorescence and absorbance applications with demanding stray light and thermal stability requirements.


      Typical Applications :

    Torus is the perfect solution for a wide range of applications where low stray light, high throughput and thermal stability are necessary:

    • Trace gas amounts in the atmosphere
    • Absorbance of optically dense solutions
    • Precision measurement of LEDs, lasers and other light sources
    • Medical dosimetry in tissue and biological media
    • Fluorescence from solid surfaces and backscattering/fluorescence in solutions and powders
    • Three Year Warranty
