Description
Technical field
The present invention relates to a kind of stray light test instrument, particularly a kind of stray light test instrument 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.
Existing stray light test instrument comprises integrating sphere, iris, detector, adjustment rack, bidimensional travel mechanism; Light source is installed on the integrating sphere shell, and scribbles diffuse-reflective material at the inside surface of integrating sphere, and iris, tested optical system and the detector of a relative side with Target Board order on same optical axis is placed on the Target Board in the integrating sphere, the integrating sphere; Tested optical system and adjustment rack all are placed on the guide rail of bidimensional travel mechanism, and detector is sitting on the adjustment rack, can do linear slide being parallel on the guide rail of optical axis.The problem that this stray light test instrument exists is: detector can only be made length and move apart from straight line on bidimensional (X, Y) direction, only depends on adjustment rack to do small moving on Y direction, thereby is only applicable to the little optical system veiling glare test of image planes; Because what adopt between adjustment rack and the guide rail is sliding contact, the slipping plane spacing is also very little, railway grease of long duration can solidify, so big, the guide rail of resistance easily produces and rocks when mobile, often cause detector rolling momentum big, bring measuring error, tested optical system volume and weight is big more, and error is big more; Tested optical system and adjustment rack all are placed on the guide rail of bidimensional travel mechanism, have reduced to detect and have adjusted efficient and reduce measuring accuracy.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of detector can do three-dimensional (X, Y, Z) direction translation in four-dimensional travel mechanism, and the stray light test instrument that can rotate around Y-axis in the horizontal direction.The test of the optical system coefficient of stray light of little image planes not only can be realized, the test of the optical system coefficient of stray light of uniformity test and the big image planes of realization can also be carried out illuminance of image plane.
Stray light test instrument of the present invention 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.When illuminance of image plane being carried out uniformity test and the optical system coefficient of stray light of big image planes is measured, can make detector translation on three-dimensional (X, Y, Z) direction, gradually whole image planes are tested.Adjustment rack rotates around Y-axis, just can carry out the veiling glare test to the optical system of sphere image planes.
Described four-dimensional travel mechanism comprises: X-direction guide rail, Y direction guide rail, Z-direction guide rail, support, adjustment rack; The X-direction guide rail is fixed on the support; The Z-direction guide rail connects with the X-direction guide rail, and the Z-direction guide rail can move as straight line along the X-direction guide rail; The top of Y direction guide rail connects with the Z-direction guide rail, and the Y direction guide rail can move as straight line along the Z-direction guide rail; The Y direction guide rail can be the central shaft rotation with its axis; Adjustment rack connects with the Y direction guide rail, and adjustment rack promptly can move as straight line along the Y direction guide rail, can rotate around Y-axis with the Y direction guide rail again; Detector is installed on the adjustment rack, can move and rotates with adjustment rack.
Ball bearing mechanism is all adopted in connection between described X-direction guide rail, Y direction guide rail, Z-direction guide rail and the adjustment rack, thereby the translation of detector and rotary resistance little, operate steadily, measuring error is little, can measure the tested optical system of large volume, big load.
Below in conjunction with the drawings and specific embodiments the present invention is described in further detail.
