Abstract
The utility model provides a stereomicroscope with an adjustable diaphragm. An adjustable diaphragm device is installed between a microscope main body and an eyepiece deflecting prism group of the stereomicroscope, and the adjustable diaphragm device has the advantages of simple structure, small size as well as easy and quick operation, and can make left and right paths of adjustable diaphragm blade groups change from the minimum light transmitting holes to the maximum light transmitting holes simultaneously by shifting an adjustable diaphragm shifter lever. Therefore, the size of the diaphragm can be adjusted at any time according to different magnifications of the microscope and lighting conditions of the observed samples, so as to match the numerical aperture of different magnifications, to reduce the influence of stray lights, and to improve the image forming quality, thereby the image forming quality is optimized.
Description
Technical field
The utility model relates to a kind of stereomicroscope, especially with the stereomicroscope of adjustable stop device.
Background technology
At present, most metaloscope and the monotubular video microscopic systems of being used for of adjustable stop device, fundamental purpose is to reduce the impact of parasitic light, improves the quality of image imaging; But be subject to the structure of stereomicroscope, seldom have the adjustable stop device to apply to the example of stereomicroscope.
Summary of the invention
For making stereomicroscope when actual observation is used, reduce the impact of parasitic light, improve the quality of image imaging, the utility model provides a kind of stereomicroscope with the adjustable stop device, its adjustable stop apparatus structure is simple, volume is little, and is simple to operate, quick, can regulate light hurdle size according to the lighting condition of microscope different multiplying and observing samples at any time, the numerical aperture of coupling different multiplying makes the quality of image imaging reach optimization.
The technical scheme that its technical matters that solves the utility model adopts is: turn at the microscope body 13 of stereomicroscope and eyepiece this adjustable stop device 3 has been installed between the prism group 2, this adjustable stop device 3 is divided into left and right sides two-way, and control arrives the light quantity of left and right sides eyepiece 1 respectively.This adjustable stop device 3 is mainly by driving gear 5, follower gear 7, trim ring 8, light hurdle sheet rotation seat 9, adjustable stop vane group 10, light hurdle sheet holder 11, adjustable stop pedestal 12, adjustable stop driving lever 15 compositions such as grade.Adjustable stop pedestal 12 is fixed on the microscope body 13 by pedestal gib screw 16, and light hurdle sheet holder 11 is fixed in the adjustable stop pedestal 12 by holder holding screw 17; One end of adjustable stop vane group 10 is installed in the mounting hole of light hurdle sheet holder 11, the other end is installed in the corresponding mounting groove of light hurdle sheet rotation seat 9, and light hurdle sheet rotation seat 9 relatively light hurdle sheet holder 11 is done clockwise or rotated counterclockwise with identical axle center.Like this, adjustable stop vane group 10 forms minimum light hole near pinhole diameter under the drive of light hurdle sheet rotation seat 9, and maximum reaches the light hole near adjustable stop pedestal 12 diameters.The screw-internal thread fit of the external thread of trim ring 8 and light hurdle sheet holder 11 can prevent that light hurdle sheet rotation seat 9 from taking off and do not affect its rotation, and follower gear 7 is fixed on the light hurdle sheet rotation seat 9 by follower gear dog screw 6; Driving gear 5 is installed on the microscope body 13 by driving gear gib screw 14 and can rotates freely, its outer knuckle-tooth and about the outer knuckle-tooth of two follower gears 7 be meshed; Non-mesh regional at driving gear 5 is screwed into adjustable stop driving lever 15, two follower gear 7 rotations about can driving under the drive of adjustable stop driving lever 15, thereby drive light hurdle sheet rotation seat 9 and do clockwise or counterclockwise rotating relative to light hurdle sheet holder 11 with identical axle center, and then make the adjustable stop vane group 10 of left and right sides two-way change to maximum light hole from minimum light hole simultaneously, thereby stir adjustable stop driving lever 15, can make the adjustable stop vane group 10 of left and right sides two-way change to maximum light hole from minimum light hole simultaneously, thereby can control the light hole that adjustable stop vane group 10 forms different-diameter, so just can control the light quantity that arrives left and right sides eyepiece 1, reach the purpose that to regulate light hurdle size according to the lighting condition of microscope different multiplying and observing samples at any time.
The beneficial effects of the utility model are obviously to reduce the impact of parasitic light when stereomicroscope is actual to be used; This adjustable stop apparatus structure is simple, volume is little, and is simple to operate, quick, can regulate light hurdle size according to the lighting condition of microscope different multiplying and observing samples at any time, the numerical aperture of coupling different multiplying makes the quality of image imaging reach optimization.
