The new 228 Series Optical Wavelength Meter from Bristol Instruments combines high accuracy and exceptional repeatability to achieve the most meaningful results for DWDM test applications. The model 228 is the ideal instrument for precise wavelength characterization of tunable DWDM lasers, DFB lasers, and VCSELs. It can also be used to calibrate passive DWDM component test equipment such as optical spectrum analyzers.
The 228 Series Optical Wavelength Meter uses a proven interferometer-based design to measure absolute wavelength to the highest accuracy available. Two versions are offered. The model 228A is used for the most demanding applications, measuring wavelength to an accuracy of ± 0.3 pm. For less exacting test requirements, the model 228B is a lower-price alternative with an accuracy of about ± 1 pm.
The accuracy of the 228 Series Optical Wavelength Meter is maintained over long periods of time because it is continuously calibrated with a built-in wavelength standard. Variation between consecutive wavelength measurements is minimized resulting in a repeatability that supports a confidence level of 3-sigma.
In addition to its reliable accuracy, the 228 Optical Wavelength Meter includes features such as short measurement time, straightforward operation, and rugged design to satisfy the needs of both the R&D scientist and the manufacturing engineer. |
