Description

For the high etendue modularization zoom lens of machine vision

Technical field

Present invention generally relates to a kind of Zoom optic lens component being used together with camera or eyepiece, the purpose is to In order to observe and check object.It is more particularly related to a kind of optical module or lens assembly be arrived, it is characterized in that having Multiple modular pieces, high etendue retention performance, wavelength calibration range be wide or zooming range is big or its characteristic group It closes.

Background technique

The history for the finite conjugate camera lens that zooming range is wide, operating distance is long can trace back to decades ago.Bausch and Lomb has used zoom modules into 7 types in 4 type of Stereo Zoom, and this module is to start manufacture in nineteen fifty-nine.Most often The amplification factor range seen is 0.7X-3X, the ratio 3/ of highest amplification factor (such as: 3X) and minimum amplification factor (such as: 0.7X) 0.7, or about 4.3,4.3:1 can be write.Fig. 1 is eyepiece used by tradition Bausch and Lomb StereoZoom4 Cabin, amplification factor range are 0.7-3X.Fig. 2 is complete stereomicroscopy used by tradition Bausch and Lomb StereoZoom4 Mirror support.

Even, in order to use stereomicroscopy camera lens can on a variety of brackets and table top, introducing a kind of name at that time It is designed for the modular in mirror cabin.The purpose of this product is in order to be used together with eyepiece magnifying glass, required for it is defined Limited field and required finite numerical aperture, to realize 2 arcs point/light pair finite resolving power.

Technological innovation is maked rapid progress, especially in the 1980s, finally carrying out along two product development routes, directly The present is still innovating.One route is related to continuing to use within the scope of stereoscope.Fig. 3 is that present traditional jeweller is still using StereoZoom microscope example.Stereoscope highest shown in Fig. 3 and minimum amplification factor ratio are 6.5:1, are usually made The zoom room for being 0.7-4.5X with amplification factor range.It can be used for a variety of different eyepiece magnifying glasses according to the optical module of Fig. 3 With Barlow camera lens, to adjust visual magnification.Another route is related to and the very phase of the monocular instrumnent used in video system As zoom room, highest amplification factor and minimum amplification factor ratio are 6.5:1.These systems can show object or scene picture Show on the sensor that one piece of diagonal line is about 11mm, normally referred to as 2/3 " frame camera.The visual field is together with about Numerical aperture (NA) after 0.0388 maximum keeps substantially uniform with original stereoscope design.Inventors believe that If be farthest used, either optimize maximum performance quality or efficiency, in principle, these cameras in other ways 0.45mm can be achieved²The greatest optical propagation of sr (square millimeter sterad), vignetting are lower than 10%.

Fig. 4 A-4C gives a kind of example of optical module in a schematic manner, and about 0.45mm may be implemented in it²sr Etendue, halation be lower than 10%.Fig. 4 A-4C gives three kinds of arrangements in a schematic manner, and low including Fig. 4 A is put Big multiple arrangement, the medium amplification factor arrangement of Fig. 4 B, the high-amplification-factor arrangement of Fig. 4 C.Optics cloth shown in Fig. 4 A-4C It sets, each includes: that first pair static doublet G10, G20, the first movable pairings are saturating from the object end to the image end of lens assembly Mirror G30, second activity doublet G50 and second couple of static doublet G60, G70.Movable doublet G30, G50 Relative to each static doublet G10, G20, G60, the position of G70 be it is adjustable, so as in the optics group of Fig. 4 A-4C An amplification factor is selected within the scope of the minimum and maximum amplification factor of part.

Present inventors have recognized that a kind of possibility, a kind of in the case where relative illumination loss is very high and/or aberration increases Biggish sensor, such as: the sensor of diagonal line length 16mm or breadth 1 ", can be with the optics combination of Fig. 4 A-4C, this Roughly the same optical module used in sample and monocular instrumnent video system can into camera 1 inch of breadth sensor field of view Image is provided, the etendue range of this camera is higher than 0.45mm²Sr, the largest of about 0.95mm²sr.But in other institutes It has ready conditions in all identical situation, this camera may show lower optimal viewing performance, or in the outside of visual field Luminance reduction, or both has.In halation or in the example of complete diagonal linear field illumination loss, reducing light vertebra angle can The achievable etendue of the highest of the optical module of Fig. 4 A-4C is fallen below 0.95mm²sr.

It is hoped that there will be a kind of cameras, may include a kind of optical module, by configuring, can reduce optical quality loss, In Higher than 0.95mm²Halation is lower than 10% within the scope of the etendue of sr.Further ideal is that have such a camera and light Department of the Chinese Academy of Sciences's part, by configuring in about 0.95-4.65 mm²It works in sr etendue range, especially this camera and optics Component can also improve performance, this can be confirmed that halation is lower than 10% by reducing light quality loss.
