Overview of Galvo Scanning Mirrors Module
Ideal for two-photon excitation microscopy, the Galvo Scanning Mirrors Module offers the best approach for fast imaging acquisition in laser scanning microscopy combined with the lowest jitter when stopped at an XY location.
The two-axis Galvo Scanning Mirrors are housed in a unit that can be utilized as a basic component for building a variety of custom instruments. The unit includes a rotating filter wheel, descanning lens, and two computer-controlled shutters. Up to four dichroic filters can be installed to separate the excitation radiation from the fluorescence; filter selection is through the software. The mirrors, 5 x 5 mm, are coated to cover the range 250 - 450 nm (UV-enhanced Al coating) or the range 375 - 800 nm (broadband dielectric coating). The unit, complete with driving electronics and power supply, is controlled through the 3-axis card by the VistaVision software.
