Photonic Sourcing

Dynamic Structures and Materials (DSM) offers custom design capabilities for rotary and linear flexure-guided stages required for unique positioning applications and environments. DSM's flexure mechanism designs are used in unique positioning applications where backlash- and stiction-free performance are critical. DSM's 3-axis rotary optic flexure mount is a representative example of DSM’s design capabilities for flexure-guided stage design. A custom, multi-axis design required three axes of flexure-guided motion for a 4 kg optic payload. The design requirements included +/- 2 mm of linear travel adjustment in one axis and +/-2 degrees of rotational adjustment in two additional axes. The assembly’s design minimizes undesirable motion during temperature transients and shock loading. DSM designed the flexure mount using a titanium and aluminum construction. Fine thread screw adjusters provide manual adjustment capability. Pre-load springs and flexure pivots provide return force. * Rotary stroke, pitch: +/- 2 degrees * Rotary stroke, yaw (manually adjustable): +/- 2 degrees * Linear stroke(manually adjusted): +/- 2 mm * Construction Materials: Titanium / Aluminum * Approximate Dimensions: 145mm x 145mm x 130mm * Scalable design for larger or smaller motions and payloads
