  • The course courseware of the self-made slide lantern machine.
  • Slide projector is an optical instrument that magnify the picture and image it on the screen.  It is an important audio-visual equipment widely used in audio-visual teaching.  The slide projector mainly consists of light source, condenser lens and projection lens.  When the transparent picture is shown, the light emitted by the light source converges through the spotlight and illuminate the picture evenly.  The picture is shown on the screen to cause the inverted image to be magnified on the screen.  The magnification of the slide projector is equal to the ratio of the lens to the screen distance to the focal length of the lens.  If you display opaque pictures or flat objects, you can use reflective slide projector.  The light emitted by a strong light source converges with a concave mirror to illuminate the pictures placed on the counter, and then the reflected light is amplified by a plane mirror and a objective lens to be shown on the screen.

The course courseware of the self-made slide lantern machine.

Slide projector is an optical instrument that magnify the picture and image it on the screen. 

It is an important audio-visual equipment widely used in audio-visual teaching. 

The slide projector mainly consists of light source, condenser lens and projection lens. 

When the transparent picture is shown, the light emitted by the light source converges through the spotlight and illuminate the picture evenly. 

The picture is shown on the screen to cause the inverted image to be magnified on the screen. 

The magnification of the slide projector is equal to the ratio of the lens to the screen distance to the focal length of the lens. 

If you display opaque pictures or flat objects, you can use reflective slide projector. 

The light emitted by a strong light source converges with a concave mirror to illuminate the pictures placed on the counter, and then the reflected light is amplified by a plane mirror and a objective lens to be shown on the screen.


Specifications:

Product material: Wood

Size: 17*7*14cm/6.69*2.76*5.51'

Age of application: over 8 years of age


Objective:
1. understand the structure and principle of telescopes and microscopes
2. recognize the importance of the application of convex lens imaging to human life and social development, and understand the sustainable development of science and technology.

Experimental cognition:
A tool used to shield the peripheral light.
Concave convex mirror: the law of the concave mirror and the convex mirror imaging follows the light reflection: the incident angle is equal to the reflection angle and the light incident along the normal point of the reflection point. The path is the same as the incident path, but the direction is opposite.

Experimental steps:
We are prepared to recognize experimental equipment: concentrator and concave convex mirror.

Experimental report:

In the hybrid optical system, the efficiency of the light source is improved due to the function of the deep ellipsoid reflector. 

The concentrator optical part is commonly used in the popular slide projector, while the concentrated light reflective hybrid optical part is often used in the more advanced slide projector. 

When the slide machine works, the light emitted by the light source is reflected on the mirror by the reflector. 

After the light is gathered, the vast majority of the light is evenly and centrally irradiated on the slide. 

The transmission light passes through the lens and shows the inverted image on the screen. 

Because the image of the convex lens is inverted, the slide must be inverted in the light path of the slide projector.
