Abstract
The utility model relates to a stray light testing device which comprises an integrating sphere, a light source, a target board, a collimation objective, a variable light railing, a detector, an adjusting rack and a four-dimensional moving mechanism. The collimation objective is mounted at one side of the variable light railing on the integrating sphere, and the target board in the integrating sphere, the collimation objective, the variable light railing, a tested optical system and the detector are orderly arranged on the same optical axis. Reflexive divergent light of the integrating sphere is converted into parallel beams through the collimation objective and irradiates the tested optical system after the beam aperture is adjusted through the variable light railing, and can carry out stray light test for limited distant object distance and unlimited distant object distance optical systems with random focus.
Description
Technical field
The utility model relates to a kind of veiling glare proving installation, particularly a kind of veiling glare proving installation of measuring optical camera lens coefficient of stray light.
Background technology
This technical indicator of coefficient of stray light is to estimate an important index of optical lens image quality.If the coefficient of stray light senior general reduces the picture contrast of image planes, as the low decline that just means optical lens target Transfer Quality of contrast, image quality is poor.So whether the testing result of coefficient of stray light is accurately most important.
The applicant on October 11st, 2007 submitted to denomination of invention for " a kind of stray light test instrument " and application for a patent for invention (number of patent application is 200710056151.9), this stray light test instrument comprises integrating sphere, light source, Target Board, iris, detector, adjustment rack, four-dimensional travel mechanism; Detector can be done three-dimensional (X, Y, Z) direction translation in four-dimensional travel mechanism, and can rotate around Y-axis in the horizontal direction.The problem that this stray light test instrument exists is: do not have the optical alignment system, only the object distance limited far away of energy measurement focal length＜300mm and infinity object distance optical system.
The utility model content
The technical problems to be solved in the utility model provides a kind of veiling glare proving installation that can carry out the veiling glare test to the object distance limited far away of any focal length and infinity object distance optical system.
Veiling glare proving installation of the present utility model comprises integrating sphere, light source, Target Board, collimator objective, iris, detector, adjustment rack, four-dimensional travel mechanism; Iris one side on the integrating sphere is installed collimator objective, and Target Board, collimator objective, iris, tested optical system and detector in integrating sphere order on same optical axis is placed.The irreflexive diverging light of integrating sphere shines tested optical system after converting parallel beam to through collimator objective again after iris is regulated light beam aperture, can carry out the veiling glare test to the object distance limited far away and the infinity object distance optical system of any focal length.
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Description of drawings
Fig. 1, being the utility model veiling glare proving installation structural representation, also is Figure of abstract.1-integrating sphere among the figure, 2-light source, 3-Target Board, the 4-collimator objective, 5-iris, the tested optical system of 6-, the 7-detector, 8-support, 9-X direction of principal axis coarse adjustment guide rail, 10-X direction of principal axis fine tuning guide rail, 11-Y direction of principal axis guide rail, 12-Z direction of principal axis coarse adjustment guide rail, 13-turntable, 14-Z direction of principal axis fine tuning guide rail, the 15-adjustment rack.
Embodiment
As shown in Figure 1, veiling glare proving installation of the present utility model comprises integrating sphere 1, light source 2, Target Board 3, collimator objective 4, iris 5, detector 7, adjustment rack 13 and four-dimensional travel mechanism; Iris 5 one sides on integrating sphere 1 are installed collimator objective 4, and the order on same optical axis of Target Board 3, collimator objective 4, iris 5, tested optical system 6 and the detector 7 in the integrating sphere 1 is placed; After integrating sphere 1 irreflexive diverging light converts parallel beam to through collimator objective 4, after iris 5 is regulated light beam aperture, shine tested optical system 6 again, can carry out the veiling glare test the object distance limited far away and the infinity object distance optical system of any focal length.Wherein collimator objective 4 adopts biconvex lens, and Target Board is placed on the focus of collimator objective 4.
