For the high etendue modularization zoom lens of machine vision
Technical field
The present invention relates to a kind of Zoom optic lens component being used together with camera or eyepiece, its purpose is to Observe and check object.It is more particularly related to an optical module or lens assembly, it is characterized in that with multiple Modular piece also has high etendue retention performance, its wavelength calibration range wide, and zooming range is big；Or with upper State the combination of characteristic.
Background technology
In the prior art, the history of the long reach finite conjugate camera lens with big zooming range, can trace back to several Before 10 years.Bausch and Lomb, in their 4 to 7 types of Stereo Zoom, used it is a kind of nineteen fifty-nine start manufacture Zoom modules.Most common zooming range manufactured by them is 0.7X-3X, and zoom ratio is about 4.3:1.Fig. 1 is with 0.7- Eyepiece cabin used by traditional Bausch and Lomb StereoZoom4 types of 3X amplification factor ranges.Fig. 2 is tradition Bausch With complete stereomicroscopy mirror support used by Lomb StereoZoom4 types.
Even at that time, being also the introduction of a kind of design of eyepiece cabin so that stereomicroscopy camera lens can in a variety of holders and It is used on table top.The said goods are to be used together with eyepiece magnifying glass, and which specify required limited field, Yi Jiwei Realize the finite resolving power of 2 arcs point/light pair, required finite numerical aperture.
Since the 1980s, technological innovation is finally pressed two product development routes and is carried out, and is still continuing so far.One Route is related to being continuing within the scope of stereoscope.Fig. 3 is today still in the traditional jeweller used StereoZoom microscope examples.Stereoscope zoom ratio shown in Fig. 3 is common 6.5:1, usually using 0.7-4.5X Enlargement ratio range zoom room.It can be used for a variety of different eyepiece magnifying glasses and Barlow mirrors according to the optical module of Fig. 3 Head, to adjust visual magnification.Another route be related to using with monocular instrumnent video system is much like, zoom ratio 6.5:1 Zoom room.Object or scene picture can be included being about on the sensor of 11mm at one piece by these systems, this biography Sensor is commonly known as 2/3 " frame camera.The visual field and 0.0388 it is approximate maximum after numerical aperture (NA) still keep with it is original Stereoscope design is roughly the same.These cameras, if farthest it is used, or in other ways to maximality Energy quality or efficiency optimize, and substantially can realize 0.45mm under near field diffraction pattern limiting condition2(square millimeter is vertical by sr Body radian) greatest optical propagation.
In Fig. 4, it is about 0.45mm to illustrate that etendue may be implemented in one kind by way of illustration2Sr, and with close Field diffraction limits the example of the optical module of performance.Fig. 4 includes three kinds of arrangements, including the low amplification factor cloth above picture It sets, intermediate medium amplification factor arrangement and the nethermost high-amplification-factor arrangement of picture.
This possibility is considered as since relative illumination loss is very big and/or aberration increases, for a kind of larger biography Sensor, such as：The sensor of the diagonal line breadths of 16mm or 1 " can be combined with the optical module of Fig. 4, in this way, and in monocular instrumnent The roughly the same optical module used in video system can be to higher than 0.45mm2Sr, the largest of about 0.95mm2The optics of sr One inch of breadth sensor field of view provides image in the camera to work within the scope of propagation.But this camera will be shown obviously Lower diffraction limit performance, or have in the external table illumination, or both that reveals reduction of visual field.
We have been desirable to a kind of camera, it includes an optical module, by configuring the light in 0.45mm2sr or more It learns in propagation range, shows near field diffraction pattern limiting performance, such as：About 0.45-0.95mm2sr or about 0.5-1 it Between etendue within the scope of.What we also wanted to is to have such a camera and optical module, by configuring in about 1- It works in 5mm2sr etendue ranges, especially this camera and optical module can also have near field diffraction pattern limiting Energy.
