Spatial Filter
-
Precise X-Y-Z alignment
-
Accepts a range of pinholes and microscope objectives
-
Slotted base for mounting onto optical breadboards
In order to transmit only the fundamental Gaussian output of a laser it is common practice to spatially filter the beam. The beam is focused onto a pinhole and then allowed to diverge or be recollimated. This spatial filter has built in X, Y motion on the pinhole mount and Z motion on the focusing objective. Pinholes in 16mm mounts are accepted as well as all standard microscope objectives. These must be ordered separately. The base has two slots for 1/4-20 or M6 screws which permit mounting onto a base with two inch or 50mm separation of mounting holes.
