  • Rotary stage for imaging a specimen
    Patent number: 7218393
    Abstract: A rotary stage (10) for use in optical projection tomography includes a stepper motor (42) with a rotatable vertical shaft (44) the lower end of which carries a specimen (28) to be imaged so that the specimen is rotated about a substantially vertical axis. The stepper motor (42) is mounted on a table (34) the position of which is accurately adjustable in tilt and in vertical position to ensure that the rotational axis of the specimen is perpendicular to the optical axis (29). The specimen (28) rotates within a stationary chamber (26) and the rotary stage is used with a microscope which provides a three-dimensional image of the specimen.
