Ocean optics introduces high transmittance, low stray light holographic concave grating spectrometer - Torus series

(Ocean Optics marine optical - www.oceanopticschina.cn) launched the aberration corrected holographic concave diffraction grating spectrometer - Torus series. The utility model has the advantages of high light transmittance, low stray light and good thermal stability, and can be used for the absorption and fluorescence measurement of liquids and solids. Torus visible band spectrometer (360nm-825nm), stray light level: at 400nm, about 0.015%, lower than the plane grating and other micro fiber spectrometer.

Flat field holographic concave grating for optical design and optical dispersion: concave grating Torus for reflection and convergence of light; grating for optical dispersion; annular grating design for aberration correction, improve diffraction efficiency. Optical resolution of Torus and higher (
