Abstract

A 3-D adjustable new type of optical bench is a 3-D adjustable mechanical device for holding optical elements, comprising a governor lever, an optical element plate and a seat, wherein the optical element plate is used for holding optical elements and can be inserted into the adjusting grooves of the governor lever; the seat is used to holding the governor lever and can fix the optical bench on the experiment table. To realize 3-D adjustment, all the adjusting points are gathered on the governor lever that is composed of a moving lever, a positioning lever and adjusting grooves; changes to relative positions of the moving lever and the positioning lever can realize adjustment of the verticality of optical element surfaces; changes to relative positions of the governor lever and the seat can realize adjustment of the height of optical element surfaces and coarse adjustment of angles; changes to parallel degrees of the adjusting grooves and the optical element plate can realize fine adjustment of the angles of optical elements; therefore the utility model can realize 3-D adjustment of optical elements, and is an adjustable device for fixing of optical elements, essentially applied to optical experiments and optical measurements.

Description

The novel optical bench that a kind of three-dimensional is adjustable

Under technical field the utility model relate to a kind of tunable arrangement of fixing optical element, the optical bench that can regulate three directions especially.

Background technology is present, known optical bench has one dimension adjustment type, two-dimensional adjustment type, be preferably the three-dimensional regulation type, the adjustable structure of three-dimensional regulation type mainly is divided into three parts: 1) Principles of Regulation of optical element vertical plane have decide the face method at 3, but implementation method is the screw that relies on three turns.Have the bottom surface depth of parallelism to regulate method, this method mainly is to regulate the levelness of optical element seat surface and then the verticality of change element by adjustable screw; 2) Gao Du adjusting is to rely on set screw that the relative position of base and support body is regulated to realize; 3) adjusting of angle is to realize by the angular adjustment of adjustable screw to three catching plates on the support body.The optical bench of this structure mainly exists some not enough: 1) 3 control methods of deciding face are loaded down with trivial details, and point of adjustment is many, generally are at least four points, so operation inconvenience; 2) method of adjusting optical element seat surface levelness though point of adjustment is few, can realize the adjusting of optical element verticality, and the adjusting of height and vertical plane influences each other; 3) because the regulator site complex structure, processing technology requires high, thus all be by the metal processing and manufacturing usually, so the effect susceptible in light damping light holophotal system, used greatly of optical bench quality.

Summary of the invention is in order to overcome the deficiency of the loaded down with trivial details and Heavy Weight of existing optical bench control method, it is a kind of to having the three-dimensional adjustable novel optical bench after the optical bench adjustment structure is improved now that the utility model provides, this novel optical bench has been realized the independent regulation of the three-dimensional of optical bench with the succinct regulative mode of its three independent regulation points, adjustment structure is simple, therefore can form with plastics and metallic combination processing and manufacturing, alleviate the weight of optical bench effectively.The technical scheme that its technical matters that solves the utility model adopts is: point of adjustment is all concentrated on the adjuster bar, add optical element plate and base and constitute the optical bench device.The optical element plate mainly is fixing optical element (as optical mirror slip) and can be inserted into the interior parts of adjuster bar adjusted groove; The main effect of base is the reference body that highly adjusting and angle rotation coarse adjustment are provided to adjuster bar, is the support component of adjuster bar, also is the connector of optical bench and shockproof table top; Adjuster bar is made up of moving bar, backstay and regulating tank three parts: the relative position that changes up-and-down rod and backstay can be realized the adjusting of optical element face verticality; The relative position that changes backstay and base can realize that optical element face height is regulated and the coarse adjustment of angle; The depth of parallelism that changes regulating tank and element board can realize the thin tuning of element angle, makes the utility model reach the purpose that can succinctly realize three-dimensional regulation easily to optical element thus.The beneficial effects of the utility model are: can be easily by the adjustings of three point of adjustment, and to the purpose of optical element realization three-dimensional regulation, the optical bench apparatus structure is simple, convenient and reliable operation, three-dimensional independent adjustable, and installation cost is cheap.
