Abstract
The invention discloses a high-contrast coaxial illumination microscope comprising a lens bracket main component, a coaxial illumination component, a converter and objective component, and a head and eyepiece component. The coaxial illumination component is provided with an illumination path. A square variable diaphragm component is fitted in the illumination path and comprises two diaphragms. Each diaphragm is provided with a V-shaped notch. The V-shaped notches of the diaphragms face each other and overlap, so that a square diaphragm hole is formed in the center of the variable diaphragm component. When the two diaphragms move toward each other, the diaphragm hole gradually diminishes until full closure. The square variable diaphragm component is disposed in the illumination path of the coaxial illumination component, so that the diaphragm hole can be closed to the minimum and corresponding adjustments of low to high power objectives are satisfied; the variable diaphragms have the advantages of simple structure, convenience in use and low cost.
Description
Technical field
The present invention relates to a kind of coaxial-illuminating microscope of high contrast type.
Background technology
The microscopical illuminating bundle of coaxial-illuminating is mapped to the observing object surface from the object lens direction, return to again the object lens imaging after being reflected by object plane, so the coaxial-illuminating microscope is mainly used in observing the opaque articles such as metal and mineral (as ore, insect, circuit board etc.), or for fluorescence microscopic analysis.So coaxial-illuminating is widely used in metaloscope, fluorescent microscope, detection microscope, be for identifying and analyze the important tool of metal inside structure organization, biological pathology analysis, industrial products evaluation.
In order all to obtain the image of high contrast at each multiple, iris is generally arranged in the coaxial-illuminating device, be used for controlling the width of light beam to change illumination, the contrast of image planes, or all be used for controlling illumination zone, enter imaging space with the restriction parasitic light, to improve the contrast of imaging.
At present, the iris that the design of iris generally adopts JB/T 9330-1999 to recommend, perhaps according to " the described iris method for designing of Optical Instrument Designing handbook, adopt single circular arc or two circular arc type light hurdle sheet, this light hurdle sheet interlocks to superpose by rotation and forms the iris hole, the quantity of light hurdle sheet is generally at 6～18, and there is defect in this structure: the thickness of light hurdle sheet is as far as possible thin; Because light hurdle sheet is very thin, so, in rotation process, light hurdle sheet has the trend of distortion, affects the formation in Guang Lan hole; Be that rotation is formed by stacking between light hurdle sheet, gap is easily arranged, cause light leakage phenomena; Moreover limit by structure, its hole, minimum light hurdle generally, more than Φ 0.6mm, tends to be greater than Φ 1mm even in practice.
In coaxial-illuminating, because object lens itself are image-forming component, it is also the collective optics of illumination, when can be full of the various object lens emergent pupil from the high power to the low power in order to make to throw light on like this, make again to make the little emergent pupil requirement to meeting object lens of light beam of light hurdle restriction when high power, often need the physical size on this light hurdle to be less than Φ 0.6mm.
In the fluorescence coaxial-illuminating, in order to slow down the cancellation of fluorescence sample, extend the service time of sample, therefore in use, as while looking for picture, location etc., often need the light hurdle can limit the illumination on-axis rays fully and enter object lens, therefore need light hurdle size can reach infinitely small.
Certainly, some microscope producer, in order to meet the height application of above-mentioned two kinds of coaxial-illuminatings, adopts the way that increases push-and-pull pin hole sideboard or sideboard, the corresponding complexity of its structure, operation inconvenience, and maloperation easily appears, even, owing to changing, cause meeting application request.
Again just like existing publication 03268368.5, description be a kind of microscopical smooth hurdle self-checking device that is applied to; It is to send pulse by single-chip microcomputer or computing machine motion controller to stepper motor, and the control step motor drives through transmission gear, adjusting gear and turning set the automatic adjusting that light hurdle sheet rotates to realize the light hurdle with direction and the speed of needs; This device is a kind of kinematic system device of realizing the automatic control and adjustment function; Complex structure, cost is higher.
