Embodiment
The utility model is further illustrated below in conjunction with Figure of description.
As shown in the figure, fixed, the one-piece type reflective eccentric analyzer of zoom includes stand type support 1, slide and match somebody with somebody in stand type support 1 Close and optical imaging system 7 is set, stand type support 1 is equipped with the rotation hand wheel 2 for being used for adjusting 7 height of optical imaging system.Optics The lower section of imaging system 7 sets XY two-dimensional movement platforms 4, and XY two-dimensional movement platforms 4 and stand type support 1 are fixed on bottom plate 3 jointly. Spherical lens detecting tool fixture 5 is set in XY two-dimensional movement platforms 4, for clamping spherical lens 6.Optical imaging system 7 wraps Include and focus attachment objective 701, zoom principal goods mirror 702, eyepiece 703, coaxial-illuminating LED information display system 704 and CCD705.Wherein zoom master Object lens 702 include the first convex lens, concavees lens and the second convex lens that are coaxially disposed, first convex lens, concavees lens and The distance between second convex lens is adjusted by the rotation of zoom main objective lens tube.As preferred structure, zoom principal goods mirror 702 Including first, second, and third lens barrel, the first convex lens, concavees lens and are respectively fixed with first, second, and third lens barrel Two convex lenses, rotatable engagement between first, second, and third lens barrel, is equipped with zoom graduation mark 706 between the first and second lens barrels, Level Four zoom graduation mark 707 between second and trinocular tube.
1. the spherical lens 6 for detecting prescribed limit incurvature radius is eccentric(Example regulation range of curvature radius be less than Equal to 300mm or more than or equal to -300mm), first install and focus attachment objective 701, by the zoom on zoom principal goods mirror 702 Graduation mark 706 rotates to " 0 " position specified, and afterwards, the light of LED is incident after the convergence of coaxial-illuminating LED information display system 704 To zoom principal goods mirror 702 and focus in attachment objective 701, by zoom principal goods mirror 702 and the folding for focusing 701 system of attachment objective Penetrate, be finally imaged onto on the centre of sphere of tested spherical lens 6, return by the reflection of the centre of sphere, the light afterwards and reenter zoom Principal goods mirror 702 and focus in attachment objective 701, by zoom principal goods mirror 702 and the refraction for focusing 701 system of attachment objective, most After be imaged onto in CCD705, when the bias of tested spherical lens 6 changes, the image on CCD705 will be shown at once Show to come.
, it is necessary to first calculate the sphere center position of tested spherical lens 6 and eccentric standard figures under above-mentioned use condition Come.As long as the radius of curvature of tested spherical lens 6 is substituted into the following formula with regard to that can draw all results.The fundamental formular being related to For:
A.n1/l+n2/l '=- (n1-n2)/R (single-spherical lens formula, spherical surface position calculate)
Wherein n1 is incident refractive index, and n2 is outgoing refractive index, and l is incident distance, and l ' is outgoing distance, and R is tested ball Face lens radius;
(eccentric calculation formula, wherein l3 are the offset on CCD to B.arctan (l3/f), and f is 702 He of zoom principal goods mirror Focus the combined focal length of attachment objective 701.
2. spherical lens of the detection in defined range of curvature radius is eccentric(Example regulation range of curvature radius is More than 300mm or less than -300mm), attachment objective 701 will be focused first and will be removed, and calculate the radius of curvature(In example with Exemplified by R500)Reflect the position of the scale on zoom principal goods mirror 702, in example, level Four zoom graduation mark 707 is moved to 1, becomes Burnt graduation mark 706 is moved to 167.44, and the light of LED incides zoom after the convergence of coaxial-illuminating LED information display system 704 afterwards In 702 system of principal goods mirror, by the refraction of zoom principal goods mirror 702, finally it is imaged onto on the centre of sphere of tested spherical lens 6, afterwards By the reflection of the centre of sphere, which returns and reenters in zoom principal goods mirror 702, by the refraction of zoom principal goods mirror 702, finally It is imaged onto among CCD705, when the bias of tested spherical lens 6 changes, the image on CCD705 will be shown at once Show to come.
It is as follows that bias calculates the key equation being related to:
A.n1/l+n2/l '=- (n1-n2)/R (single-spherical lens formula, spherical surface position calculate)
Wherein n1 is incident refractive index, and n2 is outgoing refractive index, and l is incident distance, and l ' is outgoing distance, and R is tested ball Face lens radius;
B.y = 8.25571914E-21x6 + 2.78282407E-16x5 + 3.90015002E-12x4 + 2.94198738E-08x3 + 1.28939783E-04x2+ 3.29009002E-01x + 4.57270239E+02 (Zoom system Unite non-linear focal length fit curve equation);
(eccentric calculation formula, wherein l3 are the offset on CCD to C.arctan (l3/f), and f is zoom principal goods mirror 7-2 systems System focal length).
