MicroHR Series

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:

  • UV-NIR Absorption
  • Laser characterization
  • Fluorescence
  • Atmospheric studies
  • Source characterization
Segment: Scientific
Manufacturing Company: HORIBA Scientific

Key Benefits of the MicroHR Series Spectrometers:

  • 140 mm f/3.9 Czerny-Turner with imaging optics
  • Rugged solid milled construction
  • Interchangeable dual grating turrets
  • Configurable to your requirements
  • USB 2.0 interface on automated versions

Gratings

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.
