IRIS is the first echelle spectrometer without compromises: high resolution, large bandwidth, high throughput, accurate gating, compact and robust. To show the benefits and possibilities of the IRIS echelle spectrometer we have published a white paper. Topics covered (amongst others): its unmatched throughput, UV performance, gating using a low cost CMOS camera and stability. Benchmark measurements are reported for comparison with other spectrometers.
