PATIKIL 50 Mm Focal Length Biconvex Lens Diameter 30 Mm Height 5 Mm Glass Optical Polished Round Edge Lens for Physics Experiments Clear

Color: Transparent, Material: Glass, Focal Length: 50 mm, Overall Size: 30 x 5 mm (Outer Diameter*H), Packing List: 1 x Glass Lens Advantages: Made of good quality glass, durable, scratch resistant and provides excellent optical performance. The rounded edges are polished and are not easy to hurt your hands when assembling. The biconvex lens shape provides a wide field of view and clear, sharp images. The lenses are precisely measured and have consistent curvature, ensuring consistent performance and results. Instructions: After determining the focal length, place the lens in front of the light source. The outward curved side of the lens should face 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. Application: A biconvex lens is a type of lens that is thicker in the center than at the edges, used to collect light. We can produce telescopes suitable for a variety of uses, including scientific experiments, photography, and optical instruments. CAUTION: Handle carefully to avoid scratching or damaging the lens surface. A biconvex lens is a type of lens that is thicker in the center than at the edges and is used to focus light.
