PATIKIL 10cm Focal Length 50mm Double Convex Lens and 1 Set of 10cm Focal Length 50mm Double Concave Lens for Physics Experiment Classroom Glass

Color: Transparent; Material: Glass; Focal length (double convex lens): 10cm; Focal length (double concave lens): 10cm; Diameter (double convex lens): 50mm/1.97"; Diameter (double concave lens): 50mm/1.97 "; Packing list: 2 glass lenses Advantages: Made of quality glass that is durable, scratch resistant, and provides excellent optical performance. The rounded edges are polished and will not hurt your hands during assembly. Designed with a double concave shape that diffuses light and creates a virtual image. The double-convex shape of the lens provides a wider field of view and produces clearer, sharper images. The lenses are precisely measured and have a consistent curvature to ensure consistent performance and results. Concave lens: Place the concave surface facing the lens when viewed from the object you want to disperse light from. Adjust the distance between the object and the lens until you reach the target level of dispersion. Convex Lens: After determining the focal length, place the lens in front of the light source. Make sure the curved side of the lens points toward the object you want to focus the light on. Move the lens back and forth until the image of the object is focused on the screen or surface. Applications: Double concave lenses are used to disperse light. A double convex lens is a lens that is thicker in the center than the edges and is used to collect light. You can make telescopes suitable for a variety of uses, including scientific experiments, photography, and optical instruments. Note: Double concave lenses are often used in combination with other lenses to create specific optical effects. Be careful when handling the lens to avoid scratching or damaging the surface.

How to use Concave lens: Place the concave surface facing the lens when viewed from the object you want to disperse light from. Adjust the distance between the object and the lens until you reach the target level of dispersion. Convex Lens: After determining the focal length, place the lens in front of the light source. Make sure the side of the lens that curves outward faces towards the object you want to focus the light on. Adjust the lens by moving it back and forth until the image of the object is in focus on the screen or surface.
