● Adjustable scanning range: By adjusting the cavity length of piezoelectric ceramics, different wavelengths can be scanned within a certain range. This adjustability makes it flexible for a variety of spectral analysis scenarios.

● Compact design and stability: It has a compact design for easy integration and use. Its physical structure is optimized to achieve good mechanical stability and resistance to temperature drift interference.

● High reflectivity mirror: It has high reflectivity to enhance the interference effect. The reflectivity of these mirrors is usually above 99% to improve resolution and sensitivity.

● High resolution: Able to achieve high spectral resolution, much higher than ordinary spectrometers.

● Multi-purpose: Scanning Fabry-Perot interferometers can be used in a variety of application scenarios, including laser frequency stabilization, gas spectral analysis, astronomical observation, material characteristic quantity, etc.

Response Time

The PD signal is transmitted when the 1654nm laser is swept. 

Note that no careful mode matching is performed at this time, so the peak interval is about 1.5GHz

The peak a is fitted, and the peak position and width are 99.747 and 0.071 respectively

The peak b is fitted, and the peak position and width are 134.567 and 0.069 respectively. 

The overall precision at 1654nm is about 497.4
