MicroHR Manual


The MicroHR is available in either a manual or motorized version.

The MicroHR is a short focal length Czerny-Turner spectrometer that can be used as an imaging spectrograph or a scanning Monochromator. As a spectrograph, it features either a fixed or micrometer adjustable entrance slit with out unique Quick-Align CCD adapter. The MicroHR can easily be converted to a scanning monochromator by adding a second exit slit. Equipped with an interchangeable kinematic grating mount and HORIBA Scientific's library of gratings, the MicroHR has a wavelength range that extends from 150nm to 15 µm. A high-precision wavelength counter allows for extremely accurate and repeatable wavelength positioning. First in the HR series, the MicroHR is the next generation of spectrographs and monochromators designed for high quality optical experiments.
