The HES spectrometer developed by IS-Instruments and marketed by Opton Laser is based on the concept of heterodyne spatial interferometry. This technology uses Fourier processing of the interference pattern of a Michelson-type interferometer, where mirrors are replaced by diffraction gratings, to achieve very high spectral resolution without the need for an entrance slit on the spectrometer, enabling the collection of ~ 100-500 times more signal than on a conventional Czerny-Turner spectrometer. And all in a very compact system with no moving parts.
Various cooled and uncooled detectors are available to cover the Silicon and InGaAs ranges (i.e. ~ 200 - 1700 nm). Coupling is via SMA connectors as standard (FC/PC on request) and 1 mm / NA 0.22 fibers (up to 5 mm on request). This technology is ideal for low-light applications such as Raman spectroscopy (we also offer integrated systems based on this technology), astronomical measurements or certain low-light fluorescence applications.
