How it is used
A hand lens is a convex lens used as a simple magnifier. When the object is placed just inside the focal length, the lens forms an enlarged, upright, virtual image; with the image at the near point of the eye, the magnifying power is M = 1 + D/f, where D is about 25 cm. The 50 mm lens gives a wide field of view, so a leaf, insect, mineral grain or printed scale can be seen whole while its details are enlarged.
- Hold the lens close to the eye.
- Bring the object towards the lens, or move lens and eye together, until the image is sharp.
- Let light fall on the object rather than on the lens.
- Observe and sketch the enlarged detail.
