PATIKIL Focal Length Double Concave Lens Set of 3 50mm Diameter 8mm Height Glass Optical Polished Round Edge Lens Physics Experiment Clear 4" (100mm)

Color: Transparent; Material: Glass; Focal Length: 100mm; Overall Size: 50 x 8mm/1.97 x 0.31" (Outer Diameter * Height); Packing List: 3 Glass Lenses Advantages: Made of good quality glass, 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. Lenses are precisely measured and have consistent curvature to ensure consistent performance and results. How to use: Place the concave surface facing the lens when viewed from the object you want to disperse light. Adjust the distance between the object and the lens until the desired level of dispersion is achieved. Applications: Double concave lenses are used to disperse light. Suitable for a variety of applications including scientific experiments, photography, and optical instruments. Note: Double concave lenses are often used in combination with other lenses to create specific optical effects. Double concave lenses are used to disperse light. You can make telescopes suitable for a variety of uses, including scientific experiments, photography, and optical instruments.
