HR2 Series High Resolution Spectrometers

The Ocean HR2 spectrometer provides rapid acquisition speed and excellent thermal stability for applications ranging from plasma monitoring to pharmaceuticals analysis. Ocean HR2 is compact and robust, with integration times as fast as 1 μs and thermal wavelength drift of just 0.06 pixels/° C, helping to ensure reliable spectral performance even as environmental conditions change. Ocean HR2 models cover various wavelength ranges within 190-1100 nm, with a choice of slit width sizes to help users manage throughput and optical resolution.

The HR2 high resolution spectrometers are compatible with Ocean Optics light sources, accessories and software, allowing users to optimize setups for different applications. Its rugged design, thermal stability and excellent absorbance linearity make the HR2 viable for lab use, embedding into OEM instrumentation, and integrating into process setups.
Small-footprint HR2 spectrometers are especially useful for optical emission spectroscopy applications in semiconductor environments, where spectral stability helps to ensure
precise control of wafer processes. HR2 is also a viable option for applications including blood analysis and protein concentration, where the spectrometer’s absorbance linearity (2 AU) enables quantification over a broad range of protein concentrations using a single standard curve.

HR2 high resolution spectrometers come with OceanDirect, a powerful, cross-platform Software Developers Kit with an Application Programming Interface. OceanDirect provides users with the ability to optimize spectrometer performance, access critical data for analysis, and enable High Speed Averaging Mode, a function available with newer-model Ocean Optics spectrometers that dramatically improves spectrometer signal to noise ratio performance.
