GCO-01 Spatial Filters

This device is designed for spatial filtering of an input laser beam. It is designed to eliminate any backlash during the x-y adjustment. A microscope objective (GCO-21) is used to focus the laser beam. The z motion is accomplished by another micrometer with anti-backlash mechanism. Four pinholes and a 40x/0.65 microscope objective are included. Objectives with different powers are also available, cf. (GCO-21), and should be specified when ordering. The component can be mounted on any post.
