HR6 Series High Sensitivity Spectrometers

The HR6 is a high sensitivity, high resolution spectrometer with excellent signal to noise ratio (SNR) performance for applications including absorbance of proteins and emission of broadband sources. HR6 is compact, robust and offers excellent thermal wavelength stability to ensure accurate results, even in changing ambient conditions.

Like other HR series spectrometers, HR6 models cover UV-Vis, Vis-NIR and extended-range options within the wavelength range from ~190-1100 nm, with a choice of slit width sizes to help users manage throughput and optical resolution.

Product Overview

  • High resolution performance — <1.0 nm (FWHM) with 25 µm slit (depending on configuration)
  • Excellent thermal stability — ensures reliable performance in demanding environments
  • High Speed Averaging Mode — hardware-accelerated signal averaging function that dramatically boosts signal to noise ratio
  • Configurability — multiple grating and slit options provide flexibility within range from ~190-1100 nm
  • Triggering modes — synchronize spectrometer acquisition with an external event

The HR6 high sensitivity spectrometers couple with SMA 905-terminated light sources, optical fibres and sampling accessories, allowing users to optimise setups for each application. If your measurements require sub-nanometre resolution of spectral features, the HR6 is an excellent choice. For example, the HR6 demonstrates high absorbance linearity when measuring
biomolecules, which allows users to accurately measure samples over a wide range of concentration levels. It also eliminates the need for sample dilution steps that run the risk
of introducing errors into the measurement process, helping to ensure higher quality spectra and more accurate results.

HR6 high sensitivity spectrometers come with OceanDirect, a powerful, cross-platform Software Developers Kit with an Application Programming Interface. OceanDirect allows users to optimise the spectrometers performance, access critical data for analysis, and enable High Speed Averaging Mode, a function available with our newer-model spectrometers that dramatically improves spectrometer SNR performance.
