    1) According to 3σ criterion, but never betterthan 20 % of the laser linewidth.
    2) With multimode fiber.
    3) ± 200 nm around calibration wavelength; outside of this range the accuracy is 30 MHz.
    4) ± 2 nm around calibration wavelength; outside of thisrange the accuracy is 10 MHz; note 3 also applies.
    5) 200 MHz for WS6-200 IR-III.
    6) Standard deviation. WS6-200 and higher modelsrequire singlemode or photonic cr ystal fibers to reachthis resolution.
    7) Not better than 20 % of the linewidth.
    8) Depending on PC hardware and settings. Highspeedmodels up to 76 kHz available.
    9) The CW power interpretation in [μW] compares to anexposure of 1s (generally the energy needs to be dividedby the exposure time to obtain the required power).
    10) μJ interpretation for pulsed lasers. CW signals needmore power in [μW] since the exposure is limited atIR-II instruments.
    11) Each instrument in each mode can measure lasers witha linewidth up to 30 % of the correspondig FSR.
    12) For IR instruments: 32/32.
    13) For IR-I and IR-II instruments: 16/16,for IR-III instruments: 8/80.
    14) IR-III: external calibration source needed, e.g. SLR-1532.
    15) IR instruments: external calibration source needed,e.g. SLR-1532.
    16) IR-II: > 30 min. warm-up, or until ambient equilibrium.
    17) These instruments have a decreased sensitivity by afactor of 4, compared to the Standard and IR ranges in the required input fields, respectively.
    18) 2.8 for IR-I and IR-II.
    19) 100 kHz for special ranges on request.
    20) Photonic cr ystal switches can be used up to 2000 nm.Please contact HighFinesse if you want to measureover 2000 nm.
    21) IR-III: 20 MHz.
    22) Measurement range WS7-60 IR-I: 530 – 1750 nm.
