Product Details

The HR2 spectrometer provides rapid acquisition speed and excellent thermal stability for applications ranging from plasma monitoring to pharmaceuticals analysis. 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. HR2 models cover various wavelength ranges within 340-1025 nm, with a choice of slit width sizes to help users manage throughput and optical resolution.

The HR2 spectrometer is compatible with Ocean Insight light sources, accessories and software, allowing users to optimize setups for different applications. Its rugged design, thermal stability and excellent absorbance linearity make HR2 viable for everyday lab use, embedding into OEM instrumentation, and integrating into process setups.

Product Overview

  • High resolution performance – <1.0 nm (FWHM) optical resolution

  • Rapid acquisition speed -- 1 µs minimum integration time

  • Great thermal stability -- Thermal stability to 0.06 pixels/°C

Each HR2 spectrometer comes with OceanDirect, a powerful, cross-platform Software Developers Kit (SDK) with an Application Programming Interface (API). OceanDirect provides users the capability to optimize spectrometer performance and access critical data for analysis.
