The best way to determine the absolute wavelength of CW lasers is with the 621 Series Laser Wavelength Meter from Bristol Instruments. This system provides real-time laser wavelength information with an accuracy that is guaranteed by continuous calibration with a built-in wavelength standard. The result is the reliable accuracy that ensures greater confidence in the experimental data.
Two versions of the 621 series are available. The model 621A is offered for the most demanding experiments, measuring absolute laser wavelength to the highest accuracy of ± 0.2 parts per million. For experiments that are less exacting, the model 621B is a lower-priced alternative. This system measures laser wavelength to an accuracy of ± 0.75 parts per million.
The model 621 is available in three broad wavelength configurations to satisfy virtually any experimental requirement. These ranges are the VIS (350-1100 nm), NIR (500-1700 nm), and IR (1.0-5.0 um). Measurements are made at a rate as high as 10 Hz resulting in virtually instantaneous reporting. Optical power is measured to provide a more complete analysis of laser performance. And, data can be transferred quickly and easily to a PC using a convenient USB instrument interface. |
