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

● Compact design and stability: It has a compact design for easy integration and use. Its physical structure has been 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: It can achieve high spectral resolution, which is 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 property measurement, etc.

Specification

Response Time

Transmitted PD signal when using 1063nm laser sweep. Note that no careful mode matching is performed at this time, So the peak spacing is about 1.5GHz.

The peak a was fitted and the peak position and width were 59.25 and 0.198 respectively.

The peak b was fitted, and the peak position and width were found to be 98.42 and 0.185 respectively. 

The overall result shows that the finesse at 1063 nm is about 204.5
