25mm, 40mm, 60mm Diameter Double Convex Lens Physics Teaching Tools, Convex Mirror for Magnifier, Optical Lenses Kit for Junior High School Physics Laboratory Experiment Double Concave Lens

Features

• DimensionsOur double concave/convex lens set comes in 25mm/40mm/60mm diameters - ideal sizes for telescope lenses, machine vision lens setups, and optical concave convex lens prism experiments. Perfect fit for most magnifying lenses and scientific apparatus
• High Quality MaterialCrafted from premium optical glass with precision-polished spherical lenses. The flawless convex mirror surface ensures accurate light refraction, making these high-power optical lenses reliable for laser lens applications and precise optical experiments
• Teaching ToolThese double optical lenses transform complex concepts into visible demonstrations. The clear imaging and magnification power (like Fresnel lens effects) make them exceptional magnifying glasses for classrooms, helping students grasp optics faster than textbook diagrams
• Durable and ReliableThe tempered optical glass construction resists scratches and heat - even works as fire-starting magnifying glass outdoors. Maintains stable performance whether used as science museum displays or intensive lab equipment
• Widely Used ScenariosFrom school optical experiments to research institute's laser lens studies, these concave/convex lenses serve multiple roles: science museum displays, astronomy telescope lenses replacement, DIY magnifying lenses projects, and optical glasses testing
