Description
Ocean SR4 Spectrometer Overview
The Ocean SR4 is a high-resolution spectrometer built for critical spectral analysis across UV, visible, and near-infrared ranges. Despite its compact dimensions (~88.1 × 63.5 × 31.45 mm, 275 g), it packs impressive optics and flexibility:
- High SNR up to 3000:1 (High Speed Averaging Mode) and low stray light (~2.3 AU) ensure clean spectral data.
- Multiple slit sizes (5 to 200 µm) let you optimize resolution vs. throughput for various applications.
- Versatile interfaces including USB-C, RS-232, SMA, and 16-pin Samtec TFM ensure seamless integration.
- OceanDirect SDK with API and trigger modes (e.g., synchronized acquisition) unlock automation and custom workflows.
- Built for reliability, it boasts superior thermal wavelength stability and is compatible with OceanView software for intuitive control.
Perfect for high-resolution tasks like emission line detection, plasma diagnostics, and reflectance analysis, the SR4 brings lab-level precision to compact setups.
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.
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.
