Abstract
The invention discloses an auxiliary screen for a lens imaging experiment. The auxiliary screen comprises a diaphragm screen body and a combined image screen body. The middle of the diaphragm screen body is provided with a diaphragm with the adjustable aperture. A camera is arranged over the diaphragm. One face of the combined image screen body is an image screen, and the other face of the combined image screen body is in linkage with a cylindrical connection ring. The end face of the connection ring is provided with a plane mirror. The mirror face of the plane mirror is parallel to the image screen body. By means of the auxiliary screen, the lens imaging experiment content is increased beneficially, and the lens imaging experiment effect is further improved.
Description
Technical field
The present invention relates to a kind of Experiments of Optics apparatus, be specially a kind of lens imaging experiment auxiliary screen.
Background technology
Lens imaging experiment is basic Experiments of Optics, and under paraxial rays condition, lens image formation rule obeys Gauss formula.Lens imaging experiment is measured the focal length of lens, is observed lens imaging feature by building multiple light path, checking lens image formation rule, is conducive to deepening the understanding to optical device image-forming principles such as camera, telescope, microscopes.
The people being familiar with photography knows, aperture size affect the depth of field and the imaging effect of camera imaging, but during current lens imaging tests, and lacks Germicidal efficacy and research that diaphragm affects the depth of field.When surveying the focal length of lens with autocollimation method, with plane mirror, the light reflection after lens is gone back to thing screen place and carry out autocollimation observation, because slide optical bench guide rail plugging lens and level crossing has one fixed width, make level crossing cannot near lens, cause reflected light more weak, image quality is poor, brings difficulty to the observation of reflection image.In addition, when teacher demonstrates lens imaging experiment on classroom, because picture screen is vertical with imaging optical path, student, while seeing imaging optical path clearly, is difficult to the situation seeing the upper imaging of picture screen clearly.
Summary of the invention
The object of this invention is to provide a kind of lens imaging experiment auxiliary screen being conducive to improving lens imaging experiment effect.
In order to solve the problems of the technologies described above, the present invention is achieved through the following technical solutions: lens imaging experiment auxiliary screen, comprises diaphragm screen and combination picture screen; Diaphragm screen middle part is provided with the adjustable diaphragm in aperture, is provided with the camera for capture lens imaging directly over diaphragm; The one side of combination picture screen is the picture screen for accepting lens imaging, and combination picture screen another side vertically connects a cylindrical T-Ring, and T-Ring end face is provided with level crossing, and the minute surface of level crossing shields parallel with picture.
Described camera is micro radio camera.
The present invention, owing to adopting above-mentioned design, can produce following beneficial effect: the setting of diaphragm screen can limit imaging beam, meets the imaging requirements of paraxial rays; Change the size of the aperture of the diaphragm, can the change of the Synchronous depth of field and imaging effect; Utilize camera capture lens imaging, can clear display on the display device of peripheral hardware, be convenient to experimental demonstration and observation.The level crossing of combination picture screen projection is arranged, and is convenient to survey in focal length of lens experiment at autocollimation method make level crossing near lens, can strengthen reflected light, improves image quality.The present invention is conducive to the content increasing lens imaging experiment, improves the effect of lens imaging experiment further.

Embodiment
Below in conjunction with accompanying drawing, the invention will be further described.
As shown in Figure 1, be provided with diaphragm 11 in the middle part of diaphragm screen 1, adjuster bar 13, for regulating the pore size of diaphragm 11, diaphragm screen 1 is provided with camera 12 directly over diaphragm 11.Camera 12 is micro radio camera.
As shown in Figure 2, the one side of combination picture screen 2 is picture screen 21, for accepting lens imaging; The another side of combination picture screen 2 vertically connects a cylindrical T-Ring 23, and T-Ring 23 end face is provided with level crossing 22, and the minute surface of level crossing 22 is parallel with as shielding 21.
The below of diaphragm screen 1 and combination picture screen 2 is respectively equipped with pole 123, so that on grafting slide 6 in figure 3.
As shown in Figure 3, light source 3, thing screen 4, lens 5, diaphragm screen 1, combination picture screen 2 successively activity are located on optical bench guide rail 7.Stir adjuster bar 13, regulate the pore size of diaphragm 11 on diaphragm screen 1, the Synchronous depth of field changes.Camera 12 shields lens 5 imaging on 1 rear picture screen 21 for taking diaphragm.
As shown in Figure 4, survey in focal length of lens experiment with autocollimation method, combination picture screen 2 is placed in lens 5 rear, and lens 5 are close to by level crossing 22, the light reflection through lens 5 is returned imaging on thing screen 4.
