Advantages of Solid-State, Non-Moving Optics
The significant advantage of our Fizeau-based wavelength meters, compared with other available instruments, is the absence of mechanical moving parts. This ensures the high reliability of accuracies up to 2 MHz (absolute) and the outstanding robustness HighFinesse wavelength meters are noted for. The sturdiness of this design has been proven even under extreme conditions such as freefall dropping experiments or in air-borne applications (LIDAR). Temperature and Pressure Enhanced StabilityMeasurements are temperature and pressure compensated using ultra sensitive temperature and pressure sensors. That way it is possible to use the devices in aviatic measurement environments, high altitudes, LIDAR, ...

The software also allows the user to display the idler frequency, by measuring the pump and signal laser, or by showing the frequency distance between two lasers (THz generation). Any number of long-term windows may be opened simultaneously to monitor up to 8 laser sources (multi-channel option) per wavelength meter. No other product offers this flexibility. Internal CalibrationLSA, WS5, WS6, WS6-200 and WS7 have as a standard feature automatic internal calibration. The lifetime of this maintenance-free calibration source is more than 10 years! Built-in Pulse DetectionAn integrated mechanism detects the optical peaks from a pulsed laser and starts synchronization with the measurement process. Highest SensitivityMost sensitive available detectors and special optical coatings allow highest power sensitivities down to pJ-range for small (IS-Series) and medium (LSA) spectral ranges and very good sensitivity for all ranges. | Working Principle Fizeau Interferometer |
