Replaceable Slit Spectrometers Offer Applications Versatility

Precision laser-cut slit and aperture assemblies from Ocean Optics add flexibility to the company’s Jaz, Torus and QE65 Pro miniature spectrometers. Replaceable slits give users more freedom in spectrometer design and the ability to switch easily from one application to another with the replacement of a few screws.

Modular spectroscopy makes possible thousands of applications by mixing and matching optical bench and other components in various configurations. The availability of field-replaceable slits in the Jaz, Torus and QE65 Pro spectrometers adds another layer of customer flexibility.

Spectroscopy is a technique in which the design criteria exist as a set of trade-offs. The optimal spectrometer depends upon the application. For some users, one of the most vexing trade-offs involves the choice of entrance aperture (slit). A larger slit increases throughput, but at the expense of optical resolution. A smaller slit yields higher optical resolution, but decreases throughput. Typically, changing the slit requires spectrometer rework that has to be performed at the manufacturer’s facility.

With replaceable slits, users can change the spectrometer’s performance directly in the field. Changing slits can be accomplished within minutes, without the need for realignment. For example, QE65 Pro users who need great sensitivity for low light applications such as fluorescence can change slits from a larger slit size to a small one, avoiding saturation in absorbance applications. Or a Torus configured to resolve closely aligned emission peaks for one application can be adjusted make low light level measurements for another application.
