Request InfoBristol Instruments Inc.VICTOR, N.Y., Aug. 4, 2006 -- Bristol Instruments Inc. has expanded the operational wavelength range of the infrared version of its model 621 laser wavelength meter, originally 1.5 to 4.0 µm, to 5.0 µm to satisfy new requirements for applications such as high-resolution laser spectroscopy. Two models of the 621 series are available. The 621A is used for the most demanding experiments, measuring absolute wavelength to the highest accuracy of ± 0.2 parts per million. For experiments that are less exacting, the 621B, with an accuracy of ± 1.0 part per million, is a lower-priced alternative.
