The Rhea series spectrometer offers a unique combination of ease of use and accurate measurement capabilities packed in a robust jacket. The Rhea utilizes a high-end cooled CCD detector for low noise and high dynamic range. The Neutral density filter wheel extends this dynamic range and also adds a shutter function. An ideal device for measurements where ease of use, stability, performance and price are of the essence.
