Rapid-focusing objective table device of microscope

Abstract

The invention discloses a rapid-focusing objective table device of a microscope. The rapid-focusing objective table device comprises a pedestal; three lead screws are arranged on the upper surface of the pedestal; circular sucking discs are arranged on the tops of the three lead screws; and an objective table is arranged on the circular sucking discs. A light through hole is formed in the center of the upper surface of the objective table; a glass slide is arranged above the light through hole; and a glass slide clamp is arranged on the glass slide. The glass slide clam includes a left clamp plate and a right clamp plate; and a clamp plate mounting unit is arranged at one end of each of the left clamp plate and the right clamp plate. Each clamp plate mounting unit consists of a fixed rod and a sleeve rod; the fixed rod is fixed on the objective table by a nut; a sleeve ring is arranged on the sleeve rod; one end of the sleeve ring is hinged to the left clamp plate or the right clamp plate; and anti-skid stripes are arranged on the outer surface of the sleeve rod and the inner surface of the sleeve ring. The rapid-focusing objective table device has advantages of simple structure and simple and convenient operation; the function of rapid focusing is realized; the universality of the objective table is improved; and the focusing and leveling functions of the microscope are optimized. The rapid-focusing objective table device is suitable for popularization.

Description

technical field [0001] The invention relates to the technical field of microscopes, in particular to a rapid focusing stage device for a microscope. Background technique [0002] Traditional optical microscopes generally use the method of adjusting the distance between the objective lens and the sample to achieve focusing. The focusing mechanism generally adopts the focusing method of mechanical gear reduction and gear rack cooperation, which has slow focusing speed and is easily affected by gear transmission ratio and The impact of the tooth spacing, the poor control of the focusing accuracy and other issues, especially for the objective lens microscope above 40X, it is a skill to adjust the focal length accurately. In addition, under the condition of high magnification, due to the small depth of the objective lens, The deviation of the verticality between the original stage of the microscope and the lens barrel or the unevenness of the glass slide and the sample will cause...
