Abstract
The utility model discloses an optical microscope capable of continuously changing an amplification factor. The optical microscope comprises an objective, a charge coupled deice (CCD) camera or a CCD eyepiece and a platform for placing a glass slide. The optical microscope is characterized by also comprising two adjusting devices, wherein one of the adjusting devices is used for adjusting distance between the objective and the CCD camera or the CCD eyepiece, and the other adjusting device is arranged between the platform for placing the glass slide and the objective and used for adjusting the distance between the platform for placing the glass slide and the objective; and a light-shading sleeve is arranged outside the adjusting device for adjusting the distance between the objective and the CCD camera or the CCD eyepiece. Compared with the prior art in which a limited number of amplification factors are obtained by a few of objectives with different amplification factors, the optical microscope has the advantages that: with only one microscope objective, the amplification factor of the optical microscope can be continuously changed; and during observation or measurement of the whole and details of an object, appropriate amplification factors can be obtained, the number of the objectives of the microscope is decreased, and the cost of the microscope is reduced.
Description
Technical field
The utility model relates to a kind of optical microscope of observing and measuring of being used to, and particularly relates to the optical microscope that can change enlargement ratio continuously, to be fit to that difference is observed or the requirement of measured object size.
Background technology
Optical microscope is to use the most general a kind of optical instrument that can observe and measure small items.For being applicable to the object of different sizes, optical microscope all is furnished with the different object lens of 1 cover enlargement ratio usually, like 10X, and 20X, 40X, 60X is until 100X.When observing the object of different sizes, can use different enlargement ratios instead.But cover object lens of each microscope configuration are confirmed, that is to say and can only observe object with the object lens of certain fixing enlargement ratio, and can't select only enlargement ratio according to the object size that is observed or measures.
Existing continuous zoom optical microscope all is to realize changing continuously enlargement ratio through the distance between the inner different eyeglasses of adjustment camera lens, and mechanism is very complicated like this.As patent 200410042213.7 proposed a kind of complicated mechanical mechanism guarantee change between each camera lens apart from the time each lens can be concentric continuous zoom mechanism.
Summary of the invention
The purpose of the utility model is in order to overcome existing optical microscope when observing the object of different sizes; Need use the shortcoming of different enlargement ratio object lens instead; Provide a kind of very simple realization to change the optical microscope of enlargement ratio continuously, select only enlargement ratio when be fit to observing different big wisp.
The ultimate principle of the utility model: the micro objective of design is the 160mm that confirms to the optical tube length of eyepiece when limited distance light is learned design now, when the infinity directional light designs, is 200mm.The object lens of different enlargement ratios are not always the case.In fact, if exporting micro-eyepiece or CCD camera arrangements on the different distance apart from object lens, can obtain the enlarged images of different sizes.Eyepiece or the outlet of CCD camera distance object lens are near, and the image enlargement ratio is just little, distance, and enlargement ratio is just big.Around this principle, export to the distance between eyepiece or CCD camera, just can realize the continuous variation of optical microscope enlargement ratio if continuously change object lens.When eyepiece or CCD camera are not in optical tube length 160mm or the 200mm of design; The enlarged image quality can descend to some extent; But the quality of image center section remains unchanged basically; When obtaining different enlargement ratio image, the image of high-quality part is used for observing and measuring purpose in the middle of only adopting like this.
Based on above-mentioned inventive principle; The technical scheme of the utility model is: a kind of optical microscope that can change enlargement ratio continuously; Comprise object lens, CCD camera or eyepiece, be used to place the platform of microslide; It is characterized in that this optical microscope is equipped with the adjusting gear of distance between the described object lens of adjustment and CCD camera or the eyepiece; Be equipped with the adjusting gear of distance between the platform of placing microslide and object lens between the platform of said placement microslide and the object lens; The adjusting gear that object lens and CCD camera or width between eyepiece leave is equipped with shading sleeve outward.
According to a kind of optical microscope that can change enlargement ratio continuously that technique scheme provides, continuously change the distance of CCD camera to the object lens outlet, can continuously change microscopical enlargement ratio.When observing larger object, the microscope enlargement ratio that needs is less, can regulate adjusting mechanism the CCD mobile camera moving is arrived apart from the nearer position of object lens outlet, and the image enlargement ratio that on the CCD camera, obtains like this is less, can observe this larger object well.When observing than wisp, it is big that the microscope enlargement ratio that needs is wanted, at this moment can regulate adjusting mechanism with the CCD mobile camera moving to apart from object lens outlet position far away to obtain bigger enlargement ratio.At needs some larger object is carried out overall process and minor detail when observing; Can earlier the CCD mobile camera moving be arrived apart from the nearer position of object lens outlet; Observe the overall of this larger object, slowly move the distance of CCD camera to object lens outlet then, to continuously change microscopical enlargement ratio; Until obtaining suitable enlargement ratio, details that can clear observation object.The effect of shading sleeve is to prevent ambient light influence observation or measurement.
The beneficial effect of the utility model is the continuous variation that only just can realize the optical microscope enlargement ratio with 1 microcobjective; Rather than several kinds of limited enlargement ratios that obtain of several different enlargement ratio object lens; Or adopt complicated optical system to realize changing continuously enlargement ratio; Not only make and observing or Measuring Object is overall and can obtain suitable enlargement ratio respectively during details, also reduced microscopical object lens number, reduced microscopical cost.
