Biconvex Optical Lens 36 mm Magnification 8x Converging Lens Made of Clear Optical Glass Focal Length 60 mm For Optical Experiments Education
You already have the maximum available quantity in your cart.
This converging lens with a diameter of 36 mm is made of clear optical glass and has a double convex or biconvex shape. Both sides are curved outward, allowing the lens to focus the light passing through and magnify the observed image. The lens is supplied separately without a frame and without a handle, so you can use it exactly as you wish. It is suitable for home experiments, school physics lessons, DIY projects, and for anyone interested in how optics works. The 36 mm diameter is a compromise between compactness and field of view, making the lens useful in simple magnifying kits, light experiments, and for magnifying small details.
According to the seller's specifications, the lens has a focal length of 60 mm and a magnification of 8x. It measures 6.5 mm in the centre and 2 mm at the edge, which corresponds to the typical profile of a converging lens that is thicker in the centre and tapers towards the edge. The thicker centre of the lens compared to the edge nicely illustrates the typical shape of a converging lens, which children will appreciate when first getting acquainted with optics. The smooth clear surface allows light to pass through and provides a clear view of the magnified object. The lens can be inserted into your own holder, tube, or paper model, creating a simple magnifying glass, telescope model, or other optical aid.

When handling, hold the lens by the edge to avoid leaving fingerprints on its surfaces. To clean, use a soft microfiber cloth or a cloth designed for glasses or optics. Coarse and abrasive materials may scratch the surface and reduce transparency. Store the lens in a case or soft pouch where it will not come into contact with hard objects. The glass is fragile, so protect the lens from falling onto hard floors. Also be cautious of direct sunlight, as the converging lens focuses sunlight into a single point, where high temperatures can occur. Therefore, do not leave the lens on a sunny windowsill or near flammable materials, and supervise safe handling during experiments with children.
The optical lens with a diameter of 36 mm is a practical tool for anyone wanting to learn the basics of optics in practice. With a magnification of 8x, it is ideal for viewing small objects, text, or details of nature. The optical glass lens is suitable for home laboratories, school classrooms, and DIY workshops. It can be easily incorporated into your own constructions and models, as it is supplied without a frame. Students, teachers, modellers, and DIY enthusiasts will appreciate a simple and clear biconvex lens for their projects.
