| 摘要 |
An improved microscope stand of an extremely rigid, deep-throat, substantially c-shaped, hollow construction having an extremely high effective modulus of elasticity and stiffness of an extended microscope-optic-supporting upper cantilever arm relative to a lower base portion whereby to minimize any relative vertical displacement therebetween which might tend to produce a de-focusing action of such microscope optics and adapted to controllably positionally adjustably mount a large work stage in an intermediate focusing plane within a deep-throat portion of the stand, and providing controlling large magnitude movement thereof in mutually perpendicular, substantially horizontal, x and y directions, and with the hollow construction providing interior mounting of electrical and electronic accessory equipment and maximizing the strength-to-weight ratio of the entire stand.
