摘要： A shield assembly for a built-in lens set is introduced to a lens set built in a housing, in which the lens set has an optical head and the housing provides an aperture with respective to the optical head. A protrusive enclosure surrounding the aperture protrudes toward the optical head and is spaced from the optical head by a variable slim spacing. The shield assembly includes a shield ring for sleeving both the optical head and the protrusive enclosure and an elastic connecting unit for bridging the shield ring and the housing. By providing the shield ring to enclose always the spacing and the elastic connecting unit to engage elastically the lens set with the housing, the lens set can be prevented from dust-contaminating through the aperture, aged axial offsetting problem, and poor focus-adjusting performance caused by backlash existing in a driving mechanism.

摘要： The invention relates to a microscope zoom objective lens system having improved optical performance, and comprising a compact optical system with a zoom ratio of at least 3. The microscope zoom objective lens system comprises a first lens group G1 having positive refractive power, a second lens group G2 having negative refractive power and a third lens group G3 having positive refractive power. For zooming from a low to a high magnification side, the second and third lens groups G2 and G3 move along the optical axis while the separation between the first lens group G1 and the second lens group G2 becomes wide and the separation between the second lens group G2 and the third lens group G3 becomes narrow. The first lens group G1 comprises at least one doublet having positive refractive power and consisting of a positive lens and a negative lens. The positive lens has an Abbe number defined by null>80.

The plurality of optical elements include a first optical element having two refracting surfaces and a plurality of reflecting surfaces formed in a transparent body, being arranged such that a light beam enters an inside of the transparent body from one of the two refracting surfaces and, after being successively reflected from the plurality of reflecting surfaces, exits from the other of the two refracting surfaces, and/or a second optical element having a plurality of surface mirrors integrally formed and decentered relative to one another, being arranged such that an incident light beam exits therefrom after being successively reflected from reflecting surfaces of the plurality of surface mirrors, and a third optical element composed of a plurality of coaxial refracting surfaces. In the zoom optical system, an image of an object is formed through the plurality of optical elements, and zooming is effected by varying relative positions of at least two optical elements of the plurality of optical elements.
