Abstract
The invention belongs to the field of optical measurement and relates to an optical plumbing compensator. The device consists of an equicrural reflecting prism, an upper planar lens, optical liquid, an inversion prism, a lower planar lens and a shell, wherein the lower planar lens is bonded with the edge of the bottom surface of the equicrural reflecting prism; an air interlayer is reserved at a middle light-permeable position; the upper planar lens and the lower planar lens are parallel to each other; the optical liquid is injected between the upper planar lens and the lower planar lens, and sealed by the shell; and the inversion prism is fixed at an emergent light path. Due to a corresponding relation between refraction and reflection of the optical liquid, the inversion prism and the equicrural reflecting prism, a vertically downward light beam of an object space passes through the device, and an emergent light beam always keeps constant relative to the direction of the upper planar lens and the shell and is independence of a placement attitude of the shell. The optical plumbing compensator can be widely applied to vertically upward automatic compensation for target parallel light tubes, charge coupled device (CCD) cameras and laser optical plummets.
Description
Technical field
The present invention relates to a kind of optical plumbing compensator, be used to realize that the automated optical that light points to vertically upward compensates, belong to field of optical measuring technologies.
Background technology
Production and construction and scientific experiment be unable to do without directed benchmark, and the common compensation system of precision that needs that obtains of the directed benchmark of high-precision optical is realized.At present to optical axis direction compensation way mainly contain and intersect hang spring (CN01224197.0), gravity hangs (CN200720192542.9), electron servo (CN200720093067), optics Anping CN200820231704.X mode, wherein optical compensation has reliable high precision grade characteristics.The present invention relates to a kind of optical plumbing compensator is the automatic compensation way of optics of liquids, distinguishes mode in the past.Adopt lower plane lens lower surface and isosceles reflecting prism bonding, the middle part is left the clearance and is used for total reflection, one deck optics liquid is injected in the top, liquid upper fixed inversion prism, utilize the optical match relation that light is turned back and inversion prism forms in liquid and isosceles reflecting prism, realize the automated optical compensation of pointing to vertically upward.Solved the two-dimension optical compensation that single layer of liquid is difficult to realize, reduced the number of plies of double-deck compensating liquid, helped the raising of precision and compensation range, helped the compact design of instrument internal structure, the instrument volume is greatly reduced.
Summary of the invention
The object of the invention is to provide a kind of optical plumbing compensator, and this device can compensate the collimator optical system that hangs down and put the skew of pointing to the light generation vertically upward that not gentle low frequency small angle inclination influence causes because of housing, realizes that high precision compensates vertically upward.
Technical scheme of the present invention is: a kind of optical plumbing compensator, its special character is: a kind of optical plumbing compensator, this installs by isosceles reflecting prism (1), lower plane lens (6), optics liquid (7), upward planar lens (9), inversion prism (10) and housing (14) are formed.
The lower surface of above-mentioned lower plane lens (6) and isosceles reflecting prism bottom surface (4) are bonding in edge, and the middle part is left the clearance and is used for total reflection.
Above-mentioned optics liquid (7) is injected between lower plane lens (6) and the last planar lens (9), and by housing (14) sealing, liquid surface (8) is separated with last planar lens (9).The ranges of indices of refraction of optics liquid (7) is smaller or equal to 1.50 greater than 1.49.
The vertical isosceles reflecting prism of above-mentioned incident ray bottom surface (4) incident, seeing through optics liquid (7) downwards enters in the isosceles reflecting prism (1), after isosceles reflecting prisms (1) triple reflection, from liquid surface (8) outgoing, pass through inversion prism (10) one-tenth emergent ray (11) vertically upward again.
Technical problem underlying and good effect that the present invention can solve are:
1, can realize the two dimension compensation of single layer of liquid to the exit direction of optical axis.
2, liquid level as reference application in imaging optical path, the precision height, highly sensitive, compensation range is bigger.
3, the light channel structure compactness is beneficial to the volume miniaturization Design.
