Description
Technical field
The utility model belongs to optical technical field, more specifically to a kind of to have the optics looked in the distance with microscopic function concurrently
System.
Background technology
Telescope be it is a kind of observe the conventional optical instrument away from scenery, its enlargement ratio is an important performance, multiplying power
Too small, viewing distance is not remote enough, and multiplying power is excessive, and because bore is big, weight weight, the reason such as gentle dither flow inconvenient to carry, easily
Cause observer's eye fatigue, giddy.In observing system, the principal element for determining technical device characteristic is its function and institute
The property of being solved for task.In telescopic system, the angular field of object space decides the time of search target, the amplification of instrument
Rate decides visibility distance, and Entry pupil diameters and the aberration correction of optical system then affect resolving power.Microscope is using micro- aobvious
Show optical system, for observing small items.Telescope and microscope are two kinds of different instruments, in the prior art can not
Used as telescope, the instrument used but also as microscope.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of optical system for having concurrently and looking in the distance with microscopic function.
In order to solve the above-mentioned technical problem, the technical solution of the utility model is：A kind of have concurrently is looked in the distance and microscopic function
Optical system, includes telephotolens group, inverted image microscope group and eyepiece group three parts successively, and the microscope group of looking in the distance includes successively
One concavees lens and the first convex lens, and the first concavees lens and the first convex lens mutually become placed against；The inverted image microscope group includes 2
Individual second concavees lens and 1 the second convex lens, second convex lens are positioned at the centre of two the second concavees lens, the eyepiece group
Include 1 the 3rd convex lens, 1 the 4th convex lens and 1 the 4th concave lens successively, the 4th convex lens and the 4th recessed
Mirror is mutually become placed against, and the above-mentioned lensed primary optical axis of institute is respectively positioned on straight line.
Further, the telephotolens group and inverted image microscope group can be replaced by positive lens.
Further, it is placed with graticle between the inverted image microscope group and the eyepiece group.
Further, it is placed with photoelectric sensor between the inverted image microscope group and the eyepiece group.
Using above-mentioned technical proposal, due to the setting of telephotolens group, inverted image microscope group and eyepiece group three parts so that this reality
With the new function of being provided simultaneously with looking in the distance with micro- (amplification)；When looking in the distance, system is easy to eye-observation into erect image；And micro-
System is into inverted image when (amplification)；And focal plane can place graticle, photoelectric sensor (such as CCD, CMOS) among optical system,
Realize the extension of function；The system is finally caused in the case where not increasing extra lens or lens group, to change telephotolens
Airspace between group and inverted image microscope group, you can realization is looked in the distance and the switching of micro- (amplification) function, convenient and simple for operation easy
OK.
Brief description of the drawings
Fig. 1 be the utility model as telescopic system when structural representation；
Fig. 2 be the utility model as microscopic system when structural representation.
In figure, 1- telephotolens groups, 2- inverted image microscope groups, 3- eyepiece groups, 4- exit pupil positions, 5- object planes.
Embodiment
Specific embodiment of the present utility model is described further below in conjunction with the accompanying drawings.Herein it should be noted that
It is used to help understand the utility model for the explanation of these embodiments, but does not form to restriction of the present utility model.This
Outside, as long as technical characteristic involved in each embodiment of the utility model disclosed below does not form conflict each other
Can is mutually combined.
As shown in Figure 1, 2 a kind of has the optical system looked in the distance with microscopic function concurrently, include successively telephotolens group 1,
Inverted image microscope group 2 and the three parts of eyepiece group 3, the microscope group of looking in the distance include the first concavees lens and the first convex lens, and first successively
Concavees lens and the first convex lens mutually become placed against；The inverted image microscope group 2 includes 2 the second concavees lens and 1 the second convex lens
Mirror, second convex lens positioned at the centre of two the second concavees lens, the eyepiece group 3 include successively 1 the 3rd convex lens,
1 the 4th convex lens and 1 the 4th concave lens, the 4th convex lens and the 4th concavees lens mutually become placed against, and above-mentioned institute
Lensed primary optical axis is respectively positioned on straight line.
Further, the telephotolens group 1 and inverted image microscope group 2 can be replaced by positive lens.
Further, it is placed with graticle between the inverted image microscope group 2 and the eyepiece group 3.
Further, it is placed with photoelectric sensor between the inverted image microscope group 2 and the eyepiece group 3.
Fig. 1 be the utility model as telescopic system when structural representation.The light of distant place is through telephotolens group 1 into
Vertical real image is between the L1 of airspace；Then the real image of handstand is become upright real image by inverted image microscope group 2, and image planes are positioned at sky
Between the L2 of gas interval, graticle or photoelectric sensor can be placed at the image planes；Finally by eyepiece group 3, human eye is distance L3's
