◦A well corrected achromat in the output beam of the spatial filter can be used to collimate the filtered beam.
◦The translation stage and two-axis pinhole allows the light through the objective lens to have good reproducibility..
◦Designed with an emphasis on stability, beam movement during adjustment is minimal.
◦A PA-25 (hole diameter 25μm) pinhole is included. Pinholes can be changed to match the diameter of the laser spot.
◦A Coarse/fine pinhole adjustment (SFB-16DMRO) is also available.
◦To meet a variety of requirements, the mounting position of the objective lens can be changed, allowing objective lenses with different magnifications to be used.
