AI Technical Summary

Technical Problem

Existing galvanometer mounting methods make it difficult to achieve fine adjustments, leading to scanning optical path offset and imaging distortion, and making it difficult to maintain the stability and repeatability of the galvanometer angle.

Method used

The galvanometer holder design, which uses adjusting screws to connect the galvanometer, allows for micro-angle adjustment by distributing the three adjusting screws to fix the galvanometer. Combined with the precise positioning of the semi-cylindrical groove and the galvanometer handle, it is suitable for the X-axis and Y-axis optical path requirements of two-photon microscopes.

Benefits of technology

It improves the consistency of the optical path and the stability of the scanning path, ensuring the scanning consistency of the laser spot and the coincidence of the spatial optical axis, making it suitable for high-precision two-photon fluorescence imaging systems.
