Description
Ocean SR4 Spectrometer Overview
The Ocean SR4 Spectrometer is a versatile and high-resolution instrument designed for precise spectral analysis across the UV-visible-shortwave NIR range. Anchored by a robust 3648-element CCD-array detector, this spectrometer delivers exceptional signal-to-noise ratio (SNR) performance and high-speed spectral acquisition, making it suitable for various applications in both industrial and laboratory settings. Its strong thermal wavelength stability and low stray light performance ensure reliable, reproducible results even in challenging industrial environments.
Each SR4 spectrometer is fully compatible with OceanView spectroscopy software and includes OceanDirect, a comprehensive cross-platform Software Developers Kit (SDK) with an Application Programming Interface (API). This allows users to optimize spectrometer performance and access critical data for detailed analysis. The SR4 features several trigger mode options, enabling synchronization of spectral acquisition with external events or specific sampling conditions. The High Speed Averaging Mode (HSAM) further enhances the SNR, promoting higher quality spectra and more accurate results.
Compact and highly configurable, the SR4 spectrometer offers models covering different wavelength ranges and entrance slit options to suit various analytical needs. It is compatible with Ocean Optics light sources and accessories, making it an adaptable tool for applications such as measuring spectral peaks in plasmas and emission sources or detecting subtle changes in absorbance in biological samples like DNA and proteins.
