Description
Technical field
The utility model, for junior middle school's Scientific Teaching demonstration teaching aid, is specifically related to a kind of convex lens imaging demonstration teaching aid.
Background technology
In junior middle school's teaching, convex lens problem is a large difficult point of optics teaching always.But existing teaching aid is comprehensive not to the displaying of convex lens, for presented light path, without teaching aid, demonstrate, student cannot intuitively profoundly understand intension wherein.And the instrument that we design has good intuitive and vividness, can help better the knowledge of the effect of converging of Students ' Learning convex lens and imaging.
In the 6th joint convex lens experiment of seven grades volume two first modules of existing Zhejiang religion version, experiment teaching aid is comparatively heavy, Er Ruozhuyan center, convex lens photocentre and optical screen center be at sustained height, on optical screen, can not find as time just must readjust three's height, be used in combination more inconvenient.Experiment can not demonstrate index path, and the focal length of lens can not directly be measured, and can only observe the phenomenon on optical screen, cannot make student see the most intuitively and understand light path.Due to condition restriction, what secondary school physical optical experiment was equipped with at present is all the lens of fixed focal length, if will change focal length, needs to change another lens, and expense is relatively large.
Based on above phenomenon, the design of this teaching aid has the feature of convenience, intuitive, economy.Can as in the teacher that studies science have the auxiliary content of optics class, show experimental phenomena clear and intuitively, excite student's interest, improve the quality of attending class.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of water lens that can change focal length, and can pass through atomising device display light rood to the convex lens imaging demonstration teaching aid of focal length.
The utility model is achieved through the following technical solutions: a kind of convex lens demonstration teaching aid, by light tool and optical bench, formed, light tool comprises water lens, syringe, LASER Light Source and frosted glass optical screen, optical bench comprise be positioned at the pulling and pushing little tub, be positioned at the large tub of pulling and pushing of right side of left side, with the base plank of scale be used for laying the groove of cake, described LASER Light Source is arranged on the left side of optical bench, frosted glass optical screen is arranged on the right side of optical bench, water lens are arranged on the inside of optical bench, and syringe is connected on water lens; Described groove is provided with two, and is separately positioned on and can pulls and pushes little tub and can pulling and pushing in large tub.
Convex lens demonstration teaching aid of the present utility model, described base plank one side has scale, and centre is zero graduation value, and both sides scale value is respectively to two edge heights, and water lens are fixed on the zero graduation place of base plank.
Convex lens demonstration teaching aid of the present utility model, described water lens bottom is provided with water lens carrier, is provided with two elasticity transparent rubber films on water lens.
Convex lens demonstration teaching aid of the present utility model, is decorated with grid on described frosted glass plate optical screen.
Convex lens demonstration teaching aid of the present utility model, described LASER Light Source, LASER Light Source is wrapped with the printing opacity scraps of paper of a special shape.
The beneficial effects of the utility model are: it is easy to use that this teaching aid carries arrangement, can directly adjust the height of light source, lens, optical screen, without often adjusting; By the curvature of varifocal water lens adjustment elastic transparent film, independently focus.Atomising device demonstrates light path, obtains the clear position of focus, obtain clearly as, probe into convex lens image-forming discipline.Two semi-enclosed tubs that pull and push simulation slide rail that relatively moves, conveniently reads object distance, image distance, focal length.Selection is easy, and visual phenomenon is vivid, simple to operate, and safety guarantee makes student's easy to understand, improves student's independent research capacity, and Classroom instruction quality gets a promotion.
Accompanying drawing explanation
For ease of explanation, the utility model is described in detail by following specific embodiment and accompanying drawing.
Fig. 1 is the device schematic diagram of convex lens demonstration teaching aid of the present utility model.
Fig. 2 is the varifocal water lens front elevation of convex lens demonstration teaching aid of the present utility model.
Embodiment
As depicted in figs. 1 and 2, a kind of convex lens demonstration teaching aid, by light tool and optical bench, formed, light tool comprises water lens 2, syringe 5, LASER Light Source 7 and frosted glass optical screen 4, optical bench comprise be positioned at the pulling and pushing little tub 1, be positioned at the large tub 3 of pulling and pushing of right side of left side, with the base plank 6 of scale be used for laying the groove 8 of cake, described LASER Light Source 7 is arranged on the left side of optical bench, frosted glass optical screen 4 is arranged on the right side of optical bench, water lens 2 are arranged on the inside of optical bench, and syringe 5 is connected on water lens 2; Described groove 8 is provided with two, and is separately positioned on and can pulls and pushes little tub 1 and can pull and push in large tub 3.
Convex lens demonstration teaching aid of the present utility model, described base plank 6 one sides have scale, and centre is zero graduation value, and both sides scale value is respectively to two edge heights, can directly read the distance of light source and lens and the distance of optical screen and lens, and the focal length of lens; And water lens 2 are fixed on the zero graduation place of base plank 6.
Convex lens demonstration teaching aid of the present utility model, described water lens 2 bottoms are provided with water lens carrier 10, on water lens 2, be provided with two elasticity transparent rubber films 9, water lens 2 compress by two good elasticity transparent rubber films 9 of light transmission the both sides that are encapsulated in a water proof rubber circle, formation can be held the annular seal space of water, is fixed on water lens carrier 10.
Convex lens demonstration teaching aid of the present utility model, is decorated with grid (not shown) on described frosted glass plate optical screen 4, can clearly tell the size variation of picture.
Convex lens demonstration teaching aid of the present utility model, described LASER Light Source 7, LASER Light Source 7 is wrapped with the printing opacity scraps of paper (not shown) of a special shape, can on optical screen, form clear and legible other picture, can have the various shape scraps of paper to replace.
Water lens are linked outward on syringe, by water filling or draw water, change focal length.Cake is lighted, and can obtain atomizing effect, and LASER Light Source penetrates directional light, can be observed obvious light path and light convergent point, is focus, and the corresponding scale in focus below is focal length.Movement can pull and push little tub and can pull and push large tub, changes object distance image distance, observes imaging on frosted glass plate, syringe is connected on rubber ring, discharges air, and water is injected and extracted out, the degree of convexity that changes elasticity transparent rubber film, can change focal length continuously in experimental requirement.
The above, be only embodiment of the present utility model, but protection domain of the present utility model is not limited to this, and any variation of expecting without creative work or replacement, within all should being encompassed in protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain that claims were limited.
