SR4-HR4 versatile spectrometers
Product description
The Ocean SR4 and HR4 are compact and high performance spectrometers used for diverse applications across the UV, Visible and shortwave NIR range. These multi-purpose spectrometers are 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. Thanks to its long focal length optical bench design, the HR4 can reach an optical resolution of 0.06nm FWHM.
- High resolution performance
- Superior SNR performance with HSAM mode
- Great optical bench versatility
- Excellent thermal stability: ensures reliable performance in demanding environments
