How it is used
A convex lens held closer to an object than its focal length forms an upright, enlarged virtual image. This is the simple magnifier taught in school optics. A large 3-inch lens is easy for young learners to use because a wide patch of the object is enlarged at once rather than a small spot.
- Place the object on a stable, well-lit surface.
- Hold the magnifier by its handle, keeping fingers off the lens.
- Bring the lens between the eye and the object, then move it slowly towards or away from the object.
- Stop where the enlarged image is sharpest and record what is seen.
Typical activities include observing leaf veins and plant surfaces, reading small print on maps, labels and diagrams, and comparing textures, fibres and sand or soil grains during nature-study work.
Key features
- 3-inch viewing diameter gives a wider field than a small pocket lens.
- Handheld frame lets the user adjust the working distance freely.
- Useful across biology, environmental science, general science and STEM activities.
- Portable between classroom, laboratory bench and supervised outdoor study.
- Works by optics alone, with no batteries or mains supply.
- Reusable for years when the lens is wiped clean and stored dry.
