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.
