MicroHR Series: Short Focal Length Imaging Spectrometers

HORIBA’s MicroHR spectrometer, which can be used as a scanning monochromator or an imaging spectrograph, provides exceptional performance and versatility in a compact and reasonably priced package.

The most effective gratings are used in these spectrometers, which are likewise created and produced 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

Features

Key Benefits of the MicroHR Series Spectrometers:

USB 2.0 interface on automated versions

Configurable to user requirements

140 mm f/3.9 Czerny-Turner with imaging optics

Rugged solid-milled construction

Interchangeable dual grating turrets

Gratings

Depending on the optical requirements, there is a large array of gratings to pick from. The MicroHR uses 32×32 mm gratings. There are three types of gratings: holographic, blazed holographic, and classically ruled. The dual grating turret option also allows for the ordering of a flat mirror.

Computer Control

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.

Optical Accessories

The MicroHR can be used with a wide range of optical accessories to create a unique solution.
