A tilting microscope stage enabling precise positioning of biological samples is required for a newly developed single-path holographic microscope. This thesis includes a review of currently available commercial solutions and, based on this analysis, presents an original design concept in two variants – a testing version and a final version. Using the SolidWorks software, a functional prototype of the first variant was designed, elaborated in detail, and subsequently physically realized. The prototype is based on a gimbal mechanism combined with piezoelectric actuators. Experimental measurements confirmed the correct functionality of the proposed kinematic chain and demonstrated high mechanical positioning repeatability characterized by a low sample standard deviation. The prototype testing results provide a verified theoretical and practical foundation for the future implementation of the final high-precision mechanism intended for routine laboratory operation.
