Product Details

Optimized for Performance and Versatility

SR2’s combination of speed (integration times to 10 µs) and SNR (380:1) provides application versatility without the typical trade-offs. SR2 spectrometers are well suited for applications including laser characterization, plasma monitoring, and absorbance measurements that benefit from the instrument’s high SNR performance.

Each SR2 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.

SR2 spectrometers are compact, lightweight and optimized for best performance. SR2 is compatible with Ocean Insight light sources, accessories and software, allowing users to customize setups for different applications and sampling requirements.
