Abstract
This is a kind of multifunction teaching optical bench light source and optical screen, suitable for junior middle school physics teaching.Light source part of the present utility model provides brightness stability, clearly F shapes area source, panel are marked with scale to edge contour, can measure the size of F shape area sources.The utility model light source can be sent out two parallel rays, coordinate optical bench to use the focal length that can easily measure convex lens.Optical screen part of the present utility model is marked with scale in optical screen, in that context it may be convenient to measure F shapes area source by convex lens optical screen imaging size.Because F shapes area source itself is not symmetric figure, be also easy to draw picture just, fall and left and right inverse relationship.The experiment that the utility model can be carried out has：1) focal length of convex lens is measured.2) convex lens image-forming discipline is probed into.Application method of the present utility model：1) light source and optical screen are arranged on optical bench, substitute original candle light source and common optical screen uses.
Description
Technical field：
The present invention relates to for the activity of junior physicses inquiry teaching.For completing measurement focal length of convex lens and probing into convex lens
The education activities of imaging law.
Background technology：
At present, the whole country in junior middle school physics teaching in measurement focal length of convex lens be essentially all by sunshine, by
Weather and the influence in geographical position, measurement process intuitively can not be demonstrated to student, can not more ensureing students experience, this is probed into
Process.In the education activities of convex lens image-forming discipline are probed into, national most area still uses candle light source, candle flame
Size can not measure and unstable, and profile is unintelligible, it has not been convenient to compare as and thing magnitude relationship, can not especially probe into as with
Thing this imaging law equal in magnitude.Using candle as light source, environment and air are polluted, indoor environment is stuffy, for a long time
Anoxic adversely affects to the health of teachers and students.Although there is F shape LED light sources in recent years, due to using point source of light, though
So solve pollution and safety problem, but image profiles are still unintelligible, can not solve to compare the size problem as with thing, more
Focal length of convex lens can not be measured.
The content of the invention：
The technical problems to be solved by the invention are to obtain F shape area sources using F shapes translucent sheet covering F shapes LED light source.
The light-source brightness is stable, edge contour is clear, and equipped with scale can display light source directly perceived size, the quarter on cooperation optical screen
Degree, the size of picture can be easily measured, be easy to draw the magnitude relationship as with thing in inquiry activity.Due to F shape area sources
Itself be not symmetric figure, be also easy to draw picture just, fall and left and right inverse relationship.The light source of the present invention can also project two
Bar parallel rays, the focal length for, being easy to measure lens on one point is assembled on optical screen after the converging action of convex lens, is solved
The problem of focal length of convex lens can not be measured on optical bench by perplexing numerous teachers and students for a long time.
