828 Series High-Speed Optical Wavelength Meter
Source: Bristol Instruments, Inc.
The 828 Series High-Speed Optical Wavelength Meter uses interferometer technology that is very different than that employed by other wavelength meters used for WDM wavelength testing applications. A Fizeau etalon design is used to generate a spatial interferogram that is detected by a fast InGaAs photodetector array. Using an on-board digital signal processor, the interferometric data is processed quickly into an accurate wavelength measurement. The combination of these technologies provides an unmatched, sustained measurement rate of 1 kHz.
Features Include:
- Wavelength measured to an accuracy as high as ± 0.3 pm
- Measurement rate of 1 kHz for reduced testing times
- Automatic calibration with a built-in wavelength standard
- Measurement confidence level of ≥ 99.7%
- Traceable to NIST standards
- Simultaneous measurement of optical power to ± 0.5 dB
- High sensitivity of -40 dBm (0.1 µW)
- Operates with CW and modulated signals
- Rugged design for manufacturing environments
