The optimized optical system of the Optima™ 8300 ICP-OES centers on a unique high-performance solid-state detector – the Segmented-array Charge-coupled Device (SCD) detector. A new echelle-based polychromator was designed in order to fully utilize the capabilities of the SCD. Using a PerkinElmer® echelle grating optimized for UV performance and a unique Schmidt cross-disperser grating, the Optima 8300 optical system has exceptional optical throughput and excellent resolution, providing you with superior detection limits and line selection.
