Optical Converging Lens 30 mm Magnification 10x Biconvex Lens Made of Optical Glass Focal Length 65 mm Magnifying Glass for Optical Experiments
You already have the maximum available quantity in your cart.
This converging lens with a diameter of 30 mm is made from clear optical glass and has a biconvex shape. Both sides are curved outward, allowing the lens to focus incoming light and magnify the observed image. The lens is supplied separately without a frame and 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. Due to its small diameter, this lens easily fits into small boxes, tubes, and simple models of telescopes or microscopes that you build yourself.
According to the seller's specifications, the lens has a focal length of 65 mm and a magnification of 10x. It measures 4 mm in the centre and 1.5 mm at the edge, which corresponds to the typical profile of a converging lens, being thicker in the centre and tapering towards the edge. The smaller diameter means that the lens can be easily held between two fingers and can be brought close to the eye and the observed object. The smooth clear surface allows light to pass through and provides a clear view of the magnified object. The lens can be inserted into a custom holder, tube, or paper model, creating a simple magnifying glass, telescope model, or other optical device.

When handling, hold the lens by the edge to avoid leaving fingerprints on its surfaces. Use a soft microfiber cloth for cleaning, or a cloth designed for glasses or optics. Coarse and abrasive materials may scratch the surface and impair clarity. Store the lens in a case or soft pouch, where it will not come into contact with hard objects. Glass is fragile, so protect the lens from falling on hard floors. Also, be cautious of direct sunlight, as the converging lens focuses sunlight into a single point, creating high temperatures. 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 30 mm is a practical tool for anyone wishing to learn the basics of optics in practice. With its 10x magnification, it is suitable for viewing small objects, text, or details of nature. The optical glass lens is ideal for home laboratories, school cabinets, and DIY workshops. It can be easily incorporated into your own constructions and models, as it is supplied without a frame. It will be appreciated by students, teachers, modellers, and DIY enthusiasts looking for a simple and clear biconvex lens for their projects.
