● Adjustable Scanning Range: The cavity length is adjusted by a piezoelectric ceramic, which enables the scanning of different wavelengths within a certain range. This adjustability allows it to be flexibly applied to various spectral analysis scenarios.

● Compact Design and Stability: It features 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 Mirrors: The mirrors have high reflectivity to enhance the interference effect. The reflectivity of these mirrors is usually above 99%, which improves the resolution and sensitivity.

● High Resolution: It can achieve a relatively high spectral resolution, much higher than that of ordinary spectrometers.

● Versatility: The scanning Fabry - Perot interferometer can be used in a variety of application scenarios, including laser frequency stabilization, gas spectral analysis, astronomical observation, material property measurement, and so on.

Response Time

Transmitted PD signal using 780nm laser sweep. Note that no careful mode matching was performed, so the peak spacing is about 1.5GHz.

The peak a was fitted and the peak position and width were found to be 0.059 and 0.147 respectively.

The peak b was fitted and the peak position and width were 28.97 and 0.134 respectively.

The overall result shows that the fineness at 1063nm is about 205.8 and the resolution is 1500/205.8~7.3 MHz.
