MicroHR Motorized


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

Available as an imaging spectrograph or scanning monochromator, the new automated MicroHR allows users to make rapid and precise measurements, offering a degree of versatility not found in comparable focal length spectrometers. Equipped with an interchangeable dual grating turret, the automated MicroHR operates in a wavelength range that extends from 150 nm to 15 µm. As a spectrograph, it features a fixed or micrometer entrance slit with our unique Quick-Align CCD adapter. The addition of a side exit port increases versatility, allowing for dual detector operation; collect data from a CCD in the visible region then collect data in the IR using a single channel detector. The convenience of a USB interface allows users to scan and acquire data through a single computer connection. A rugged, high throughput optical system, the MicroHR is an ideal, affordable tool for a wide range of spectroscopic applications.
