Abstract
A sample holder apparatus for a top-loading cryostat insert based on a cage assembly system which is mounted onto a vacuum flange. The vacuum flange has a group of blind bores on the vacuum side of the flange, in which are mounted hollow cage assembly rods, and a further corresponding group of four blind bores on the air side of the flange for receiving further cage assembly rods. A cage assembly system can thus be provided on the vacuum side of the flange and, if desired, extended through the vacuum flange onto the air side with optical communication between the vacuum and air sides taking place through a window at the top of the flange. Feed-throughs on the flange provide for access of optical fibers and electrical leads. The design provides a sample holder which is readily adaptable and reconfigurable to perform a variety of optical experiments in a top-loading cryostat. Examples of near-field scanning microscopy (NSOM) and confocal microscopy are described.
