It can make telescopes, suitable for a variety of applications, including scientific experiments, photography, and optical instruments. Specification Color: Transparent Material: Glass Focal Length: 100mm Overall Size: 50 x 9mm \/ 1.97 x 0.35 inch(OD*H) Packing List: 1 x Glass Len Advantage Made of quality glass that is durable, scratch resistant, and provides excellent optical performance. Round edges have been polished, it is not easy to hurt your hand when you assemble it. The double convex shape of the lens provides a wider field of view, resulting in clearer and sharper images. The lens is accurately measured and has consistent curvature, ensuring consistent performance and results. Instruction Once you have determined the focal length, position the lens in front of the light source. The side of the lens that is curved outward should face the object you want to focus the light on. Move the lens back and forth until the image of the object is in focus on the screen or surface. NOTE: Remember to handle the lens with care to avoid scratches or damage to the surface.\u003c\/p\u003e\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e✅ Color: Transparent; Material: Glass; Focal Length: 100mm; Overall Size: 50 x 9mm \/ 1.97 x 0.35 inch(OD*H); Packing List: 1 x Glass Len\u003c\/li\u003e\n\u003cli\u003e✅ Advantage: Made of quality glass that is durable, scratch resistant, and provides excellent optical performance.
