Abstract
The utility model provides a portable many light sources newton rings demonstration appearance should demonstrate the camera lens of appearance and place in the symmetric position of newton rings optical axis with hair glass, light source placed is on hair glass, and the light of light source is directional hair glass's same region all, and the battery connects gradually the light source through master switch and change over switch, and for the light source power supply, the camera links to each other with the camera lens, the camera shooting to the image pass through the USB line and export. The beneficial effects are that this demonstration appearance can be watched the newton rings interference pattern like directly offering up a sacrifice many people through computer and projection at the screen. The magazine design has guaranteed that the image shooting does not receive external disturbance. Many light sources switch the different interference that can observe polychromatic light (white light) and monochromatic light. Small in size, portable has solved the problem that the lecture experiment enters the classroom.
Description
Technical field
The utility model relates to a kind of demonstration instrument, particularly a kind of portable multiple light courcess Newton's ring demonstrationInstrument.
Background technology
Newton ' s ring device is a device being made up of planoconvex spotlight and plate glass, the convex surface of planoconvex spotlightAnd between plate glass, form the air film of axial symmetry type, the axis that its symmetry axis is planoconvex spotlight. WhenWhen light source direction of illumination and direction of observation (or lens shooting direction) are symmetrical about this symmetry axis, (follow lightReflection law) be observable or photograph Newton ring interference pattern. Newton ring interference is College Physics lightThe representative content that the department of the Chinese Academy of Sciences divides, observes newton ' s ring device heavier in experiment, need sodium vapor lamp, reading micro-Mirror etc. Demonstration instrument in the market also volume is larger, and inconvenience is carried on teaching classroom and demonstrates.
Summary of the invention
For the defect of prior art, the purpose of this utility model is to provide a kind of portable multiple light courcess newtonRing demonstrator, this demonstrator volume is small and exquisite, simple to operate, safe and reliable, can directly pass through computer-projectorObserve the Newton ring interference pattern of light sources with different wavelengths, be applicable to coordinate College Physics in multi-media classroomTheory Course is carried out simultaneous classroom demonstration.
For achieving the above object, the technical solution adopted in the utility model is to provide a kind of portable multiple light courcessNewton's ring demonstrator, wherein: this demonstrator includes shell, and shell is provided with cover plate, in shell, comprisesHave Newton's ring, video camera, camera lens, frosted glass, light source, battery, master switch, change-over switch, shell,Cover plate, USB line.
Described camera lens and frosted glass are positioned over the symmetrical region of Newton's ring optical axis, and described light source is positioned over a mao glassOn glass, the light of light source all points to the same area of frosted glass, and this region and camera lens are about Newton's ringOptical axis symmetry, battery is connected light source by master switch successively with change-over switch, is light source power supply, shootingMachine is connected with camera lens, and the image that video camera photographs is exported by USB line.
Effect of the present utility model is:
(1) Newton ring interference image directly can be watched for many people with being projected on screen by computer.
(2) magazine design has ensured that image taking is not subject to external interference.
(3) multiple light courcess switching can be observed polychromatic light (white light) and monochromatic different interference.
