◦Since the objective lens is fitted with a linear motion stage with screw to adjust focal point position, and the pinhole is fitted with a precision two-axis pinhole holder to adjust in-plane position, spot light of the laser will pass the pinhole with good reproducibility.
◦Have an overall tilt adjustment mechanism.
◦A well corrected achromatic in the output beam of the spatial filter can be used to collimate the filtered beam.
