3pcs 31mm Diameter Double Convex Lens, Glass Optically Polished Concave Mirror Round Edges Double Optical Lens for Physics Experiment, Kaleidoscope,Telescope

Features

• Color: Clear; Material: Optical Glass; Overall Size: 31mm/0.98nch(OD); Packing List: 3 x 31mm Double Convex Lens
• Advantage: Crafted from high-quality optical plastic, this double convex lens is lightweight yet durable, resistant to impacts and scratches. The edges are finely smoothed to ensure safe handling during installation. Its precisely designed double convex structure offers enhanced light-gathering ability, producing bright and vivid images. The concave mirror is manufactured with strict dimensional accuracy, guaranteeing stable optical performance.
• Instruction: First, identify the focal length. Place the optical lenses so that the convex side faces the light source. Adjust the position of the lens along the optical axis until the desired achieved on the target surface or screen. Experiment with different distances to optimize the clarity and sharpness of the image.
• Application: Ideal for DIY optical projects, such as constructing simple microscopes or magnifiers. The optic kit can also be used in educational demonstrations of light refraction and focusing principles, suitable for both classroom and home use.
• Note: Keep the magnifying lens away from high temperatures and harsh chemicals to maintain its optical integrity. Always clean it gently with a soft, lint-free cloth to avoid scratches.
