Best Choice of Spherical Lens
According to the refraction of light and Snell's law, light will be refracted at the interface between the optical material and the air, resulting in a change in the direction of light propagation. Parallel rays of light converge to a point after passing through a double-convex lens and plano-convex lens. They diverge after passing through a double-concave lens and plano-concave lens. After the optical design, optical lenses converge and scatter the light, which plays the role of collimation, relay and imaging. Due to the different shapes of optical lenses, the light transmission effect, imaging effect and spherical aberration are also different. Plano-convex lenses are suitable for the following situations: 1. Spherical lenses are used for infinity conjugate. 2. Object and image are located at different distances from spherical lenses. 3. The object is at infinity and the image is in focus. 4. Converging parallel light. 5. Turn the light of the point light source into a para
