PATIKIL 1300mm Focal Length Biconcave Lenses, 2 Pieces, 75mm Diameter, 6mm Height, Glass Optical Polishing, Round Edge Lenses, Clear, for Physics Labs

Color: Transparent, Material: Glass, Focal Length: 300mm, Overall Size: 75 x 6mm (Outer Diameter * H), Packing List: 2 x Glass Lenses Advantages: Made of high-quality glass that is durable, scratch-resistant, and provides excellent optical performance. The rounded edges are polished for ease of assembly. It features a double-concave design that diffuses light and creates a virtual image. The lens is precisely measured and has a consistent curvature, ensuring consistent performance and results. Instructions: Place the concave side of the lens toward the object you want to disperse light from. Adjust the distance between the object and the lens until the desired dispersion level is achieved. Applications: Biconcave lenses are used to disperse light. They can be used to create telescopes suitable for a variety of applications, including scientific experiments, photography, and optical equipment. Note: Biconcave lenses are often used in conjunction with other lenses to create specific optical effects.
