Request InfoBristol Instruments Inc.Bristol Instruments said its 621-series laser wavelength meters from offer accurate, real-time wavelength information for continuous-wave (CW) lasers. Two versions are available: The model 621A is for the most demanding experiments, measuring absolute wavelength to an accuracy as high as ± 0.0001 nm. For experiments that are less exacting, the model 621B is a lower-priced alternative. This system measures laser wavelength to an accuracy of ± 0.001 nm. The accuracy of the 621 is guaranteed, because it is continuously calibrated with a built-in HeNe laser wavelength standard.
