The SR4 is a high performance spectrometer with high-speed spectral acquisition and excellent signal-to-noise ratio (SNR) performance for diverse applications across the UV-visible-shortwave NIR range. This multipurpose spectrometer is anchored by a 3648-element CCD-array detector and robust electronics to deliver measurement capabilities on the line or in the lab. Strong thermal wavelength stability and low stray light performance ensure reliable, reproducible results, even in challenging industrial environments.

Each SR4 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.

SR4 is highly configurable, with models covering different wavelength ranges from approximately 190-1100 nm and entrance slit options in widths of 5 µm to 200 µm. The SR4 spectrometer is compact, versatile and compatible with Ocean Insight light sources and accessories. SR4 demonstrates effective results for applications from measuring distinct spectral peaks within plasmas and emission sources to detecting subtle changes in absorbance in DNA, proteins and other biological samples.
