Abstract
The invention discloses an optical microscope capable of continuously varying an amplification factor. The optical microscope comprises an objective lens, a CCD (Charge Coupled Device) camera or an eye lens, and a platform used for arranging a glass slide, and is characterized in that: an adjusting device is provided, and is used for adjusting the distance between the objective lens and the CCD camera or the eye lens; an another adjusting device is arranged between the objective lens and the platform used for arranging the glass slide; and a light shading sleeve is arranged at the outer part of the adjusting device which is used for adjusting the distance between the objective lens and the CCD camera or the eye lens. The optical microscope has the beneficial effect of capability of continuously varying the amplification factor of the optical microscope by using only one microobjective, without adopting several objective lenses with different amplification factors to obtain several limited amplification factors, so that proper amplification factors can be respectively obtained to observe or measure the general overview and details of an object, the number of the objective lenses of the microscope is also reduced, and the cost of the microscope is lowered.
Description
Technical field
The present invention relates to a kind of optical microscope of observing and measuring of being used to, particularly relate to the optical microscope that can change enlargement ratio continuously, to be fit to the requirement of different observed or measured object sizes.
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, as 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 determined, 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 object size observed or that measure.
Existing continuous zoom optical microscope all is to realize changing continuously enlargement ratio by the distance of adjusting between the inner different eyeglasses of 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
Purpose of the present invention 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.
Ultimate principle of the present invention: the micro objective of design is the 160mm that determines to the optical tube length of eyepiece when limited distance light is learned design now, is 200mm when the infinity directional light designs.The object lens of different enlargement ratios are not always the case.In fact, if micro-eyepiece or CCD camera arrangements are exported on the different distance at the distance 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 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 the optical tube length 160mm of design or 200mm, the enlarged image quality can descend to some extent, but the quality of image center section remains unchanged substantially, 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, technical scheme of the present invention is: a kind of optical microscope that continuously changes enlargement ratio, 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 adjusting distance between described object lens 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 described placement microslide and the object lens; Object lens and CCD camera or width between eyepiece from adjusting gear outside be equipped with shading sleeve.
According to a kind of optical microscope that continuously changes enlargement ratio 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 obtains on the CCD camera 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, slow then mobile CCD camera is to the distance of object lens outlet, 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 invention has the beneficial effects as follows the continuous variation that only just can realize the optical microscope enlargement ratio with 1 microcobjective, rather than limited several enlargement ratios of obtaining 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 reduce microscopical object lens number, reduced microscopical cost.
