RS4k Spectrometer
The Redback Systems RS4k is a compact, fibre-coupled echelle spectrometer designed for medium-resolution spectroscopy across the ultraviolet, visible, and near-infrared spectral range. The spectrometer is available in two wavelength configurations covering 220–850 nm or 300–850 nm, each providing a resolving power of R~4,000. Its compact and robust design makes the RS4k well suited for cost-effective Raman spectroscopy, plasma spectroscopy, and optical emission analysis.
UV-NIR Spectroscopy Applications
The RS4k spectrometer is suitable for:
Laser-induced breakdown spectroscopy (LIBS)
Simultaneous multi-element analysis
Endpoint detection in deposition and etching of semiconductor materials
The device integrates with our RedSolve data visualization software, allowing you to view the full spectrum in detail.
Back-illuminated CMOS detector
The RS4k is equipped with the latest generation of back-illuminated CMOS sensor technology, delivering exceptional sensitivity across the ultraviolet, visible, and near-infrared spectrum. With a 12-bit dynamic range, low noise, and high-speed readout, the RS4k offers a powerful blend of performance and affordability, ideal for demanding spectroscopy applications.
High Throughput
The RS4k operates with small-core multi-mode fibres, optimizing light throughput and making it particularly well-suited for low-light applications.
