Alignment mirrors maybe purchased separately (see Section 3.7). Alignment of the spatial filter involves: stripping down the KT311(/M), coarse alignment of the beam to the table, placement of the KT311(/M) in the beam, fine alignment of the optical path, installation of the focusing lens, and installation and adjustment of the collimating lens. -

“B” to adjust the height of the laser beam so that it is 4.19" (105.6 mm) above the optical bench. At this point it is assumed that the laser beam is pointed in a direction that will allow the KT311(/M) to be inserted close (within a few inches) to the mirror mount. -

Spatial Filter System Chapter 3: Operation Instructions 4. Once the stripped down KT311(/M) is in alignment, three table clamps should be used to secure the KT311(/M) in position. Thorlabs’ CL series table clamps are recommended. Check the alignment of the beam through the system to ensure movement of the KT311(/M) did not occur during clamping 5. -

Spatial Filter System Chapter 3: Operation Instructions light will pass through the pinhole. The light passing through the pinhole will create a spot. This spot should be used as a guide to peak the laser with the XY translator. 3. Slide the Z translator until the beam is focused through the pinhole. Slowly lock each screw on the Z translator and peak the XY translator to maintain throughput. - Page 10 Use the alignment tools to locate the centers of the locations specified below. 1. Use Mirror “B” to carefully center the beam on the input of the KT311(/M) in both the horizontal and vertical planes. Note the position of the beam at the output. Is it high or low? Or is it to the right or left? 2.
