* - each subrange is covered by an exchangeable optics set (NL crystals, beamsplitters, filters, photodetectors). A set for one of the subranges of the customer's choice is supplied with the unit, additional sets are supplied upon request; the final set of optics and detectors depends on the specifications of the sources to be measured and is discussed with our sales manager upon offering; ** - typical values, depends on input pulse duration and wavelength.
