## Features

- Studenglass: principle- a convex lens is made according to the principle of refraction of light. the parallel light is incident into the convex lens parallel to the main optical. after the light is refracted twice on both sides of the lens, the light is concentrated on a point on the. this point is called the point of the convex lens.
- Science classroom optics kits: convex len dia: 3cm.
- Lab kit: lightweight and portable: this optical convex lens has two different sizes and lengths, which can present different optical effects. you can choose the appropriate size and length according to your needs. the size is small, easy to carry, and easy to store.
- Glass magnifying glass: multipurpose: our double convex lens is versatile and can be for multiple applications, such as magnifying small objects, creating images, and even starting fires.
- Concave lenses for science: scope of application: this optical convex lens is mainly suitable for adults and , and is suitable for scientific experiments, physics teaching, application of optical principles, classroom demonstrations and other occasions, with a wide range of applications.
