Description
Technical field
The present invention relates to optical mirror slip field of test instrument, particularly a kind of anti-transmission Eccentric Instrument test platform and anti-transmission Eccentric Instrument.
Background technology
Optical lens is requisite critical component in various optical imaging systems, monitoring system. The quality good or not of optical lens directly affects the performance quality of imaging system, monitoring system, has even determined success or not. Because optical lens must exist various aberration defects in theory, so often adopt the optical mirror slip combination of comparatively complicated difformity different materials in the time that optical lens designs, object is the various aberrations of calibrating optical camera lens, to obtaining the image quality of high-quality. But design is accomplished to really to create and also has a lot of errors, in manufacturing the process of optical lens, reality has unavoidably various part foozles, camera lens is debug error etc. Generally have higher tolerance although the eyeglass of optical lens, lens barrel, spacer ring etc. affect the part of optical system imaging quality, even so, these residual tolerances bring impact still can to the image quality of whole camera lens.
The quality requirement of contemporary optics system is more and more higher, for some special high-grade, precision and advanced purposes, the optical system quality degradation that the glasses lens eccentricity of several microns causes is intolerable, and therefore the accurate control of eccentricity of glasses lens and adjustment have become the bottleneck of optical lens manufacturing technology. And current anti-transmission Eccentric Instrument great majority can only testing lens the wherein offset of one side, external advanced anti-transmission Eccentric Instrument can be measured the offset on eyeglass two sides by two-beam source, but this anti-transmission Eccentric Instrument is expensive, production cost is increased, be not suitable for wide model application; Therefore, need to develop at present the high and applicable wide model application of a kind of low cost, strong operability, accuracy can testing lens two sides offset anti-transmission Eccentric Instrument.
Summary of the invention
The technical problem to be solved in the present invention is, provide a kind of simple in structure, cost is low, strong operability, can assist the test platform of the accurate testing lens of anti-transmission Eccentric Instrument two sides offset.
In order to solve the problems of the technologies described above, the technical solution used in the present invention is, this anti-transmission Eccentric Instrument test platform comprises eccentric fixture and lens receptacles tool, described eccentric fixture comprises support, described support along continuous straight runs extension is provided with a platform, and one end of described platform is provided with opening along its longitudinal direction, and described platform is provided with first in a side of aperture position and tightens knob, described platform is provided with cavity in the inner side of described opening, and described cavity is for providing the space of clamping described lens receptacles tool; Described lens receptacles tool comprises adapter and interface unit, is provided with a zero diopter sheet in described adapter, and a side of described adapter is provided with connection vacuum extractor; The center of described interface unit is provided with a measured hole, and described adapter is movable with described interface unit and is closely connected; Described lens receptacles tool is put eyeglass to be tested for being.
Adopt technique scheme, eyeglass to be tested is put in to the upper end of lens receptacles tool, by vacuumizing, it is steadily adsorbed, and lens receptacles tool is placed on the circle cavity of platform of eccentric fixture, and by first tighten knob eccentric fixture is tightened fixing, the offset of one side that can testing lens; In the time wanting the another side of testing lens, first unclamp first and tighten knob rotating eccentricity fixture, take out and be placed with the lens receptacles tool of eyeglass to be tested gently, and be inverted, then be placed on the circle cavity of platform, carry out the test of another side offset; This test platform architecture is simple, strong operability, and cost is low, is suitable for wide model and applies.
The present invention further improves and is, this anti-transmission Eccentric Instrument test platform is provided with the first base, and the support of described the first base and described eccentric fixture is activity and is rotatably connected.
