1) ± 200 nm around calibration wavelength; outside of this range the accuracy as WS7-30.

2) ± 2 nm around calibration wavelength; outside of this range the accuracy as WS8-10; note 1) also applies.

3) Standard deviation. WS6-200 and higher models require singlemode or photonic crystal fibers to reach this resolution.

4) The CW power interpretation in [μW] compares to an exposure of 1s (generally the energy needs to be divided by the exposure time to obtain the required power).

5)  Each instrument in each mode can measure lasers with a linewidth up to 30 % of the correspondig FSR.

6) 100 kHz for special ranges on request.
