The Ocean SR2 spectrometer is a versatile spectrometer that provides high-speed spectral acquisition and delivers best-in-class signal-to-noise ratio (SNR) performance. The Ocean SR2 is ideally suited for applications including laser characterization, plasma monitoring, and absorbance measurements that benefit from the instrument’s high SNR (380:1) performance. Ocean SR2’s combination of speed (integration times to 10 µs) and SNR provides application versatility without the trade-offs typical of comparable spectrometers. Ocean SR2 is highly configurable and is produced using industry-leading manufacturing techniques, ensuring excellent thermal stability and low unit-to-unit variation. Preconfigured models are available with entrance slits in widths of 5 µm to 200 µm, providing users with a range of optical resolution (FWHM) and signal-throughput options to meet various requirements. The Ocean SR2 is compact and remarkably versatile, and is compatible with Ocean Insight light sources, accessories and OceanView software, allowing users to optimize setups for different applications.
