What is F theta lens? F theta lens is a specific type of lens commonly used in laser systems, particularly in laser marking, engraving, cutting, and scanning applications. The lens is designed so that the image height and scanning angle satisfy the relationship formula y=f*θ (θ is the deflection angle of the galvanometer), so the […]

The difference between CW and QCW CW (Continuous wave) As shown in Figure 1, the laser works in a continuous manner, and the energy of the output beam remains constant and uninterrupted. Usually has lower peak power and higher average power. Widely used in metal cutting, copper-aluminum welding, optical fiber communication, etc. QCW (Quasi-continuous wave)
Recently, Duke University release their latest research paper of Real-time three-dimensional single-particle tracking (RT-3D-SPT). “With the new galvo-based implementation, notable increases in tracking duration, localization precision, and the degree to which the objects are locked to the center of the detection volume were observed. These results suggest faster control response elements can expand RT-3D-SPT to
