Finescope FS-60 Series

Click to Enlarge    The FS-60 is a microscope unit made for brightfield inspection. It is ideal for observing very minute sections, and especially suitable for the Prober and Failure Analysis Manufacturing applications. High magnification, long working distance, fiber optic cold light illumination ensures easy and accurate operation.

    The FS-60FD offers the option for use of Mitutoyo's darkfield lenses. A special nosepiece is provided to accommodate these objectives.

    The FS-60YC is designed for a YAG cutting laser. An infrared radiation compensation system is built into the FS-60YC optics. Note: 1x fixed magnification safety filter for laser.

    The plan achromatic FS-ULWD series objectives have the world's longest working distance and an infinite tube system. These lenses provide flexible observations at high magnifications and independent correction of lateral chromatic aberration.

    The field of view is extra wide and erect. The fiber optic cold light illumination keeps the system free from thermal expansion caused by illumination heat. A color video system and photography unit are also available for this unit.
