Abstract
The utility model provides a built-in coaxial illumination stereo microscope. Two sets of built-in coaxial illumination devices are installed below lenses of two front fixed objective sets. The built-in coaxial illumination stereo microscope overcomes the defects that an oblique illumination system stereo microscope and a vertical illumination system stereo microscope are distorted in image, poor in contrast and low in image resolution; and by adopting the built-in coaxial illumination stereo microscope, the observed object has no shadow, an undistorted image can be observed, the image is high in contrast and resolution, and the imaging quality of the image is substantially improved.
Description
Technical field
The utility model relates to a kind of stereomicroscope, the especially built-in stereomicroscope of in-line illumination device.
Background technology
On existing stereomicroscope, light source adopts skew ray illuminator and the circular lamp that is arranged on micro objective lower end outer cover to fall to penetrating lighting system more, these two kinds of lighting systems all exist illuminating ray and object plane off plumb situation, the place of object plane fovea superior may be blocked by protruding place and be produced shade, when observing object plane, easily cause profile chap or distortion, thereby poor contrast, image definition is not high, and the image quality of image is observed in impact.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of stereomicroscope of built-in in-line illumination device, before two, fixedly two groups of built-in in-line illumination device have been installed in object lens arrangement of mirrors sheet 7 lower ends, illuminating ray are irradiated to observe object plane back reflection to return microscopical time and do not produce because being blocked the phenomenon that produces shade by protruding place in the place of object plane fovea superior.
The utility model solves the technical scheme that its technical matters adopts: this built-in coaxial-illuminating stereomicroscope is comprised of the symmetrical light path in two of left and right, left optical routing eyepiece group 2, composite prism group 3, rear fixedly object lens arrangement of mirrors sheet 4, zoom arrangement of mirrors sheet 5, compensation arrangement of mirrors sheet 6, front fixedly object lens arrangement of mirrors sheet 7, semi-transparent semi-reflecting eyeglass () 8, focus lamp group (one) 9, LED lamp () 10 forms, wherein semi-transparent semi-reflecting eyeglass () 8, focus lamp group (one) 9, LED lamp () 10 forms left path built-in formula in-line illumination device; The built-in in-line illumination device of right wing is by semi-transparent semi-reflecting eyeglass (two) 13, and focus lamp group (two) 14, LED lamps (two) 15 form; The LED lamp (one) 10 of two-way is connected with the mode of LED lamp (two) 15 use series connection, and by independently circuit control box 12 controls of outside, and brightness can regulate.After the light line focus mirror group (two) 14 of LED lamp (two) 15 transmittings focuses on, by semi-transparent semi-reflecting eyeglass (two) 13 reflections, to object plane 11, thrown light on again, from the light of object plane 11 reflections, enter left light path, see through semi-transparent semi-reflecting eyeglass () 8, through front fixedly object lens arrangement of mirrors sheet 7, compensation arrangement of mirrors sheet 6, zoom arrangement of mirrors sheet 5, after the fixedly amplification of object lens arrangement of mirrors sheet 4, arrive composite prism group 3 and carry out entering after the turnover of light eyepiece group 2 and amplify and focus in image planes 1; In like manner, after the light line focus mirror group () 9 of LED lamp (one) 10 transmitting focuses on, by semi-transparent semi-reflecting eyeglass (one) 8 reflection, to object plane 11, thrown light on again, from the light of object plane 11 reflections, enter right light path, see through semi-transparent semi-reflecting eyeglass (two) 13, then by right light path remainder, be finally imaged in right image planes.
The beneficial effects of the utility model are, the image fault that this built-in coaxial-illuminating stereomicroscope has overcome skew ray illuminator stereomicroscope and fallen to penetrating lighting system stereomicroscope, poor contrast, the shortcomings such as image definition is not high, make to observe object and there is no shade, can observe undistorted image, picture contrast is high and clear, greatly improves the image quality of image.
Accompanying drawing explanation
Fig. 1 is the stereomicroscope optical system schematic diagram that the utlity model has built-in in-line illumination device.
In figure: 1 image planes, 2 eyepiece groups, 3 composite prism groups, 4 rear fixedly object lens arrangement of mirrors sheets, 5 zoom arrangement of mirrors sheets, 6 compensation arrangement of mirrors sheets, 7 front fixedly object lens arrangement of mirrors sheets, 8 semi-transparent semi-reflecting eyeglasses (), 9 focus lamp groups (), 10 LED lamps (), 11 object planes, 12 circuit control boxes, 13 semi-transparent semi-reflecting eyeglasses (two), 14 focus lamp groups (two), 15 LED lamps (two).
Embodiment
Below in conjunction with accompanying drawing, the utility model is further illustrated.
As shown in Figure 1, this built-in coaxial-illuminating stereomicroscope is comprised of the symmetrical light path in two of left and right, left optical routing eyepiece group 2, composite prism group 3, rear fixedly object lens arrangement of mirrors sheet 4, zoom arrangement of mirrors sheet 5, compensation arrangement of mirrors sheet 6, front fixedly object lens arrangement of mirrors sheet 7, semi-transparent semi-reflecting eyeglass () 8, focus lamp group () 9, LED lamp (one) 10 forms, semi-transparent semi-reflecting eyeglass () 8 wherein, focus lamp group (one) 9, LED lamp () 10 forms left path built-in formula in-line illumination device; The built-in in-line illumination device of right wing is by semi-transparent semi-reflecting eyeglass (two) 13, and focus lamp group (two) 14, LED lamps (two) 15 form; The LED lamp (one) 10 of two-way is connected with the mode of LED lamp (two) 15 use series connection, and by independently circuit control box 12 controls of outside, and brightness can regulate.After the light line focus mirror group (two) 14 of LED lamp (two) 15 transmittings focuses on, by semi-transparent semi-reflecting eyeglass (two) 13 reflections, to object plane 11, thrown light on again, from the light of object plane 11 reflections, enter left light path, see through semi-transparent semi-reflecting eyeglass () 8, through front fixedly object lens arrangement of mirrors sheet 7, compensation arrangement of mirrors sheet 6, zoom arrangement of mirrors sheet 5, after the fixedly amplification of object lens arrangement of mirrors sheet 4, arrive composite prism group 3 and carry out entering after the turnover of light eyepiece group 2 and amplify and focus in image planes 1; In like manner, after the light line focus mirror group () 9 of LED lamp (one) 10 transmitting focuses on, by semi-transparent semi-reflecting eyeglass (one) 8 reflection, to object plane 11, thrown light on again, from the light of object plane 11 reflections, enter right light path, see through semi-transparent semi-reflecting eyeglass (two) 13, then by right light path remainder, be finally imaged in right image planes.Because the angle between the symmetrical light path in two of left and right and the normal of vertical direction is very little, so incident illumination light is substantially perpendicular to object plane 11 and throws light on, illuminating ray being irradiated to observe object plane back reflection to return microscopical time does not produce because being blocked the phenomenon that produces shade by protruding place in the place of object plane fovea superior, thereby can observe undistorted image, picture contrast is high and clear, greatly improves the image quality of image.
