Abstract
The utility model relates to a portable micro-telescope consisting of an ocular, a primary lens cone and a micro-objective. The primary lens cone is also detachably connected with a focusable secondary lens cone. The micro-objective consists of two groups of lenses, wherein one group of lenses is fixedly arranged on the primary lens cone, and the other group of lenses is fixedly arranged on the secondary lens cone. When the primary and the secondary lens cones are combined together, a microscope with reading function can be obtained. After the primary and the secondary lens cones are separated from each other, the ocular, the primary lens cone and one group of objective lenses form a telescope, while the other group of objective lenses forms a magnifier. The portable micro-telescope has simple structure and low cost and is extremely convenient to use and carry.
Description
(1) technical field
The utility model relates to a kind of portable micro-telescope.
(2) background technology
Microscope equipment is very wide in the usable range in fields such as printing, weaving, biology, experiment, but mostly volume is bigger, complex structure, and the cost height uses and carries inconvenience, and function singleness.
Chinese patent 99207446.0 has been introduced a kind of vertical reading microscope, has changed above-mentioned deficiency, but only has micro-function, the function of not looking in the distance.
Chinese patent CN1521520A discloses the optical devices that a kind of microscope and telescope can fast transition, utilizes the monotropic focus lens of liquid to form object lens and eyepiece, realizes that microscope and telescope can fast transition.Liquid charges in the transparent plastic sheet of two circular seal and forms the monotropic focus lens of liquid, change the focal length that how much can change eyeglass of liquid in the monotropic focus lens of liquid, the monotropic focus lens of this liquid can be realized changing fast each other as the microscope and the telescope of object lens and eyepiece formation.
(3) summary of the invention
Technical problem to be solved in the utility model is to provide that a kind of volume is little, simple in structure, cost is lower, easy to use and carry and portable micro-telescope with micro-and the function of looking in the distance.
Described portable micro-telescope, be made up of eyepiece, body tube and microcobjective, described body tube also removably is connected with adjustable focus secondary mirror tube, and microcobjective is made up of two set of contact lenses, wherein a set of contact lenses is fixedly mounted on the body tube, and another set of contact lenses is fixedly mounted on the secondary mirror tube.
Further, described eyepiece is threaded with body tube.
Further, described body tube is threaded with the secondary mirror tube.
Further, described eyepiece is the adjustable focus eyepiece.
Further, be provided with other Chinese roof prism in the described body tube.
Further, be provided with the graticule that possesses the reading function between described eyepiece and the other Chinese roof prism.
Further, described secondary mirror tube front end also removably is connected with the transparent support frame, and bracing frame is provided with the opening of being convenient to adjust object space.
Further, described secondary mirror tube is threaded with bracing frame.
Major-minor lens barrel of the present utility model is a microscope with reading function when combining, after major and minor lens barrel is separated, eyepiece, body tube and wherein one group of object lens constitute a telescope again, another group object lens then constitute a magnifier.The utility model is simple in structure, and cost is low, use and very convenient to carry.

Fig. 1 is the structural representation of the utility model during as microscope equipment.
Fig. 2 is the structural representation of the utility model during as telescopic system.
Fig. 3 is the structural representation of the utility model during as magnifier apparatus.
(5) embodiment
Below by embodiment the utility model is preferably specified, but protection domain of the present utility model is not limited to this.
With reference to Fig. 1, a kind of portable micro-telescope, form by eyepiece 1, body tube 2 and microcobjective, described body tube 2 also removably is connected with adjustable focus secondary mirror tube 5, microcobjective is made up of two set of contact lenses, wherein a set of contact lenses 3 is fixedly mounted on the body tube, and another set of contact lenses 4 is fixedly mounted on the secondary mirror tube 5.
Described eyepiece 1 is threaded with body tube 2.
Described body tube 2 is threaded with secondary mirror tube 5.
Described eyepiece 1 is the adjustable focus eyepiece.
Be provided with other Chinese roof prism 6 in the described body tube 2.
Be provided with the graticule 7 that possesses the reading function between described eyepiece 1 and the other Chinese roof prism 6.
Described secondary mirror tube 5 front ends also removably are connected with transparent support frame 8, and bracing frame 8 is provided with the opening 9 of being convenient to adjust object space.
Described microcobjective 3 is selected two gummed convex lens for use, and focal length is f1=104mm, and the focal length of eyepiece 1 is f2=13mm.Also select two gummed convex lens for use at the added microcobjective 4 in body tube 2 fronts, its focal length is f=81.5mm, it forms a combination microcobjective together with the microcobjective 3 on the body tube 2, the magnification of this combination microcobjective is the ratio of two focal lengths, that is: M1=f1/f=104/81.5=1.276, and the magnification of eyepiece is: M2=250/f2=19.2, so overall amplification is during as reading microscope: M=M1*M2=1.276*19.2=24.5, approximate 25 times, this is one 25 times a reading microscope.
When major and minor lens barrel separated, body tube 2, eyepiece 1 and object lens 3 promptly constituted a telescope, and as shown in Figure 2, its magnification is exactly: M=f1/f2=8.Object lens 4, secondary mirror tube 5, transparent support frame 8 then constitute a magnifier, as shown in Figure 3.
By optical design, the different eyepieces and the focal length of object lens can be selected, thereby the telescope and the microscope of different enlargement ratios can be obtained, do not repeat them here.
