Technical field
The present invention relates to a kind of Zoom optic lens components being used together with camera or eyepiece, and its purpose is to see Examine and check object.Specifically, the present invention relates to an optical module or lens assemblies, it is characterized in that: having multiple modularizations Part, high etendue retention performance, wavelength calibration range be wide or zooming range is big or its property combination.
Background technique
The history of long reach finite conjugate camera lens with big zooming range can trace back to decades ago.At that time, Bausch and Lomb, into 7 types, has used a kind of zoom mould for starting manufacture in nineteen fifty-nine in their 4 type of Stereo Zoom Block.The manufactured most common zooming range is 0.7X-3X, and zoom ratio is about 4.3:1.Attached drawing 1 are as follows: there is 0.7-3X times magnification Eyepiece cabin used by traditional Bausch and Lomb StereoZoom4 of number range.Attached drawing 2 are as follows: traditional Bausch and Complete stereomicroscopy mirror support used by Lomb StereoZoom4.
Even then, it is also the introduction of a kind of eyepiece cabin design, so that stereomicroscopy camera lens can be in a variety of brackets and platform It is used on face.The product is to be used together with eyepiece magnifying glass, and which specify required limited fields, and for reality Finite numerical aperture required for the finite resolving power of existing 2 arcs point/light pair.
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 continuing to use within the scope of stereoscope.Attached drawing 3 is today still in the traditional jeweller used StereoZoom microscope example.Attached stereoscope zoom ratio shown in Fig. 3 is common 6.5:1, usually using 0.7- The zoom room of the enlargement ratio range of 4.5X.According to the optical module of attached drawing 3, can be used for a variety of different eyepiece magnifying glasses and Barlow camera lens, to adjust visual magnification.Another route be related to using with monocular instrumnent video system is much like, zoom ratio For the zoom room of 6.5:1.These systems can show object or scene picture on one piece of sensor for being about 11mm, This 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 Stereoscope design originally is roughly the same.These cameras, if be farthest used, or right in other ways Maximum performance quality or efficiency optimize, and substantially can realize 0.45mm under near field diffraction pattern limiting condition2Sr (square Millimeter sterad) greatest optical propagation.
Attached drawing 4 illustrates a kind of about 0.45mm that etendue may be implemented by way of illustration2Sr, and have close The example that field diffraction limits the optical component of performance.It include three kinds of arrangements in attached drawing 4, including the low magnification cloth above picture It sets, intermediate medium amplification factor arrangement and the nethermost high-amplification-factor arrangement of picture.
This possibility, it is considered to be since relative illumination loss is very big and/or aberration increases.For a kind of biggish biography Sensor, such as: the sensor of the diagonal line breadth of 16mm or 1 ", it can be in conjunction with the optical component of attached drawing 4.In this way, and in attached drawing About the same optical module used in 3 microscopes can be to higher than 0.45mm2Sr, the largest of about 0.95mm2The optics of sr expands The magazine one inch of breadth sensor field of view run within the scope of exhibition amount provides image.But this camera will be shown obviously Lower diffraction limits performance.
