Focusing Lens
★Exhibit Content: Popular science on lens imaging principles and light refraction laws ★Interaction: Manual interactive experiment ★Operation: 1. Press the button to turn on the light source; 2. Observe the image on the screen; 3. Move and combine various lenses to guide the light and try to produce a clear image; 4. Understand the imaging characteristics and their causes. ★Exhibit Description: The exhibit consists of an LED light source, multiple sets of lenses with different focal lengths, a movable imaging screen, and an operation console. It is a recommended exhibit from the PopsciCat Exhibit Store. Visitors press the button to activate the light source, freely move and combine the lenses, and try to form a clear image on the screen. By observing changes in image size, orientation, and virtual/real nature, they can understand the relationship between focal length, object distance, and image distance, as well as imaging characteristics. This exhibit transforms abstract optical formulas into intuitive hands-on experiments, suitable for visitors of all ages to explore light refraction and lens imaging principles. ★Scientific Principle: A lens is an optical element that can transmit and refract light, converge or diverge light beams, and can present small objects on a screen for easy viewing. The size of the image presented on the screen depends on the distance from the lens to the light source, i.e., the focal length of the lens.
