Axis-adjustable optical device and optical instrument utilizing the same

Abstract

An axis-adjustable optical device includes: a base; a first adjustment unit including a biasing component disposed between a support seat and the base, and a plurality of screw fasteners for coupling the support seat to the base; a second adjustment unit including a guide hoop coupled and pivotable relative to a pivot seat on the support seat; and a lens unit including a barrel that defines an optical axis, and that has a first segment having a universal coupling relation with a holding seat on the support seat, and a second segment having the guide hoop sleeved thereon. Pivotal movement of the guide hoop relative to the pivot seat drives movement of the barrel to adjust the optical axis.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]This application claims priority of Taiwanese Application No. 094146181, filed on Dec. 23, 2005.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]The invention relates to an optical instrument, more particularly to an optical instrument including an axis-adjustable optical device.[0004]2. Description of the Related Art[0005]As shown in FIG. 1, a conventional telescope is an optical instrument that incorporates both digital recording and distance measuring functions. The conventional telescope includes a main body 10, and first, second and third optical devices 11, 12, 13.[0006]The main body 10 includes a mounting seat 101 that extends upwardly.[0007]The first optical device 11 has telescopic and laser-emitting functions. The first optical device 11 is coupled to the main body 10, and has a first optical axis (I1). The first optical device 11 includes a first objective lens unit 111 to be disposed to confront a target object, ...

AI Technical Summary

Benefits of technology

"The present invention provides an optical device with an axis-adjustable lens unit. The device includes a base, first and second adjustment units, and a lens unit. The first adjustment unit includes a support seat, at least one biasing component, and screw fasteners for coupling to the base. The second adjustment unit includes a holding seat, a pivot seat, and a guide hoop. The lens unit includes a barrel with a universal coupling relation to the holding seat of the second adjustment unit. Pivotal movement of the guide hoop relative to the pivot seat drives movement of the barrel such that the optical axis is adjusted in the second and third directions. The technical effect of the invention is to provide an optical device with easy axis adjustments."

Problems solved by technology

However, during actual manufacturing and axis adjustment processes, the following problems are encountered due to the structure of the conventional telescope, especially with the second optical device 12:

In addition, after the second optical device 12 has been mounted to the mounting seat 101, it is required to dismount the second optical device 12 from the mounting seat 101 if the first, second and third optical axes (I1), (I2), (I3) are not parallel in order to repeat the axis adjustment process, which is inconvenient and time-consuming.
