Abstract
Provided is a metallographic microscope which comprises a lighting system and an imaging system. The lighting system comprises a halogen bulb, a non-spherical surface condenser, a color filter, a condenser, a reflector, a condenser, a semi-reflector and an objective lens. The imaging system comprises a polarization analyzer, a light reflector, a lens, a reflector, a field lens, a reticule, a reflector, a lens, a rotary prism, an imaging lens, a double-eye observation system and an ocular. The utility model is characterized in that in the lighting system, an arc dimming plate, a filament image elimination grating and a changeable aperture is arranged between the color filter and the condenser. The utility model has the advantages of realizing even changes of brightness from the visual field center to the edges and totally eliminating the filament image.
Description
Technical field
The utility model relates to a kind of metaloscope.
Background technology
The accurate optical viewer that microscope is more common.But present microscope has following defective:
1) light and shade brightness in visual field changes inhomogeneous; 2) can not eliminate the filament picture fully.
The utility model content
The technical problems to be solved in the utility model provides a kind of metaloscope; This microscope can be realized the center, visual field to edge light and shade brightness even variation, and can eliminate the filament picture fully.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: a kind of metaloscope, and it comprises: illuminator and imaging system;
Described illuminator comprises: based on halogen bulb, aspherical condenser, color filter, condenser, catoptron, condenser, half-reflecting mirror and object lens;
Described imaging system comprises: analyzer, reflective mirror, lens, catoptron, field lens, graticule, catoptron, lens, turn to prism, imaging len, binocular viewing system, eyepiece;
In the described illuminator, be provided with the circular arc dimmer board between described color filter and the condenser, the filament that disappears is as grating and iris; When illuminator was done the bright field observation, the big trumpet of iris was regulated in Φ 2～Φ 10mm scope; And when making dark field and observing, the size of iris is then regulated in Φ 19～Φ 28mm scope.
The described filament that disappears is the regular hexagon grating filter as grating; The described filament that disappears is 14 millimeters as the diameter of grating 5,1 millimeter of thickness; 0.3 millimeter of the length of side of regular hexagon grating wherein, 0.6 millimeter of diagonal angle line length.
Described circular arc dimmer board upper and lower thick middlely becomes inner concavity circular arc; And the one side on top will be grown than another side.
The utlity model has and to realize the center, visual field, and can eliminate the advantage of filament picture fully to edge light and shade brightness even variation.
Description of drawings
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail
Fig. 1 is an optical system diagram of the present utility model;
Fig. 2 is that the filament that disappears of the present utility model is as the optical grating construction synoptic diagram;
Fig. 3 is a circular arc light modulation plate structure synoptic diagram of the present utility model.
Embodiment
Shown in Fig. 1-3, the utility model illuminator and imaging system;
Described illuminator comprises: based on halogen bulb 1, aspherical condenser 2, color filter 3, condenser 6, catoptron 7, condenser 9, half-reflecting mirror 11 and object lens 12;
Described imaging system comprises: analyzer 13, reflective mirror 14, lens 15, catoptron 16, field lens 17, graticule 18, catoptron 19, lens 20, turn to prism 21, imaging len 22, binocular viewing system, eyepiece 24;
In the described illuminator, be provided with circular arc dimmer board 4 between described color filter 3 and the condenser 6, the filament that disappears is as grating 5 and iris; When illuminator was done the bright field observation, the big trumpet of iris was regulated in Φ 2～Φ 10mm scope; And when making dark field and observing, the size of iris is then regulated in Φ 19～Φ 28mm scope;
The described filament that disappears is regular hexagon grating filters as grating 5; The described filament that disappears is 14 millimeters as the diameter of grating 5,1 millimeter of thickness; 0.3 millimeter of the length of side of regular hexagon grating wherein, 0.6 millimeter of diagonal angle line length.
Described circular arc dimmer board 4 upper and lower thick middlely becomes inner concavity circular arc; And the one side on top will be grown than another side
Principle of work of the present utility model is as follows: the light by based on halogen bulb (1) sends, through after the illuminator, focus on the back focus of object lens (12), and the process object lens vertically illuminate and are observed specimen surface again.Sample is through object lens (12) the amplification imaging first time, through half-reflecting mirror (11), reflective mirror (14), lens (15), catoptron (16) and (19), lens (20), turn to prism (21), imaging len (22) amplification imaging on eyepiece 24 front focal planes, again through eyepiece 24 amplification for the second time and observed by human eye.
Obviously, the foregoing description of the present utility model only is for the utility model example clearly is described, and is not to be qualification to embodiment of the present utility model.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here can't give exhaustive to all embodiments.Everyly belong to the row that conspicuous variation that the technical solution of the utility model extends out or change still are in protection domain of the present utility model.
