Short Focal Length Imaging Spectrometers
Available as an imaging spectrograph or a scanning monochromator, HORIBA’s MicroHR spectrometer offers excellent flexibility and performance in a small and affordable package. These spectrometers benefit from the highest quality of gratings, also designed and manufactured by HORIBA. A rugged, high throughput optical system, the MicroHR is an ideal, affordable tool for a wide range of spectroscopic applications such as:
There is a wide selection of gratings to choose from depending on optical requirements. Gratings are 32 x 32 mm for the MicroHR. There are three different types of gratings available; classically ruled, holographic, and blazed holographic. There is also a flat mirror that may be ordered for the dual grating turret option. Please click on the link below to view all our grating options.
In addition to wavelength control the MicroHR has an optional automated turret control and automated control of the optional internal five position filter wheel. There are multiple software platforms to choose from for spectrometer control and acquisition. Please click on the link below to view all our software choices.
The MicroHR is compatible with many optical accessories to create your custom solution. Please click on the link below to view some of our optical accessories.
