Specialized Spectrometers: High Resolution and High Speed Options

Ocean Insight spectrometers are versatile enough for a wide range of applications. But sometimes, a configuration that’s more applicable to your specific measurement requirements is the best option.

High Resolution Spectrometers - HR Series

Although we highly recommend the HR4Pro – its performance makes it the best choice for the broadest range of high-resolution applications – there may be occasions where choosing another HR model makes sense. Our Application Engineers can help you decide.

High Resolution Spectrometers for Laser Characterization

Modular spectrometers can be used to characterize laser output, either as part of an internal laser feedback loop or externally. Ocean Insight HR series spectrometers can be configured for sub-nanometer optical resolution (FWHM) performance in the UV-Vis (200-875 nm), Vis-NIR (350-1025 nm) and UV-Vis-NIR (200-1100 nm) ranges, with fast response times and triggering functions for synchronizing laser events to spectral acquisition.

Combined Wavelength and Power Monitoring

Laser diodes are prone to wavelength and power output fluctuations due to temperature variations, often requiring feedback loops and stabilization. The HR4Pro is a compact, thermally stable monitoring solution that fits into a laser system or sub-assembly and can accommodate both fiber and free-space coupling. Typical measurements include spectral radiant flux and integrated laser power.

Additional Laser Characteristics

The HR4Pro can be used for more than measuring a center wavelength. HR4Pro spectrometers are offered in different wavelengths and with your choice of slit widths, allowing you to home in on a specific wavelength range. With this flexibility, you can use a single spectrometer to measure multiple characteristics of the laser including peak location, FWHM, integrated area under the peak, and other parameters.

Lasers such as tunable Ti:sapphire lasers, OPOs and supercontinuum lasers also require ongoing spectral characterization, which is where HR series spectrometers can provide a convenient, modular option. Whether measuring center wavelength, spectral shape or power, HR spectrometers are convenient, low-cost tools for the characterization and monitoring of many types of laser sources.
