Abstract
A flexure mount for economically producing pure translational motion with no arcuate or error motion in the vertical direction utilizing alignment pins and parts reducing structures including monolithic springs. A low profile embodiment utilizes a compound monolithic spring. The flexure mount may be used to translate a mirror or retroreflector in a purely linear direction of precisely controlled and known distance, useful in myriad interferometer applications including spectroscopy.
Claims6
A precision instrument flexure mount comprising:
- a. a base;
- b. an actuator having a fixed relationship to the base;
- c. a frame mounted on the base comprising:
- i. two compound monolithic springs, each spring having a cross piece, two vertical pieces with bottom ends and a spring central piece with a bottom end;
- ii. a plurality of transverse members, each transverse member is fastened to a top frame portion with at least a portion of one spring cross piece held therebetween;
- and
- iii. the bottom end of the spring central piece fastened between a carriage connection member and a carriage member;
- iv. the bottom end of each vertical piece fastened between a base connection member and the base;
- and
- d. a translation arm attached adjacent a first end to the actuator and adjacent a second end to a precision instrument element, a central portion of the translation arm extending through the frame and attached to the carriage member, the actuator imparting a force on the arm, whereby translation of the arm through the frame is constrained to one orthogonal axis.
