Abstract: Provided is a solid immersion lens (SIL) holder for optical axis precision correction of a high resolution optical microscope, equipped with a SIL and an objective lens barrel equipped with a plurality of objective lenses, the SIL holder comprising: a circular flange providing in the middle of the objective lens barrel to be coupled to the SIL holder; a coupling flange formed at one end portion thereof and coupled to the circular flange; a conical tube formed at the other end portion thereof, the SIL being mounted onto a lower end portion of the conical tube, wherein the SIL holder comprises an optical axis adjusting part which adjusts such that the central axis of the SIL approaches the central axis of an objective lens, and the SIL holder comprises an extension/contraction adjusting part which allows the SIL to be very close to a measurement surface of a specimen.

Abstract: Provided is a method of manufacturing a diamond knife for an ultra-microtome, including determining a shape and size of a knife, performing a multiphase flow analysis on movement of a droplet at a fore-end of the knife with the determined shape and size, processing a fine pattern to ensure hydrophobic property according to a result of the flow analysis, and grinding a blade of the knife after the processing of the fine pattern to minimize an interval between the pattern and the blade and, thus, a knife blade is always maintained in a wet state due to a droplet movement between a hydrophobic fine pattern and a hydrophilic surface to continuously generate ultrathin slices.
