A pocket loupe or hand lens is an essential part of the naturalist's field kit. Whether your interest is in plants or insects, rocks or small mammals, a magnifying lens will allow you to observe the finer details which will improve both your identification skills and your overall appreciation for the intricacies of the natural world.
This Opticron Hand Lens contains a high quality 23mm doublet lens and provides excellent distortion-free magnification. The 10x magnification is recommended for general observations and this magnifier is the one most commonly recommended for all types of fieldwork.
When not in use the PMMA lens pivots inside the brushed alloy metal casing so that it is protected from scratches and knocks. This also makes it very compact and it will easily fit into a pocket or bag. This hand lens also has a useful metal loop for attaching a neck cord.
To use a hand lens hold it close to your eye then bring the specimen up to the lens until the point where it is in focus.
I got one of these last year as I'm interested in botany. It's a good one to get if you're just starting out, and I was pleased with it. But now, less than 12 months later, the little screw has fallen out and gone missing! Can it be replaced? Why do they have such a component that can work itself loose in this product? What can I say apart from that if you get one, then you'll have to keep an eye on the screw and make sure it's screwed in. Why can't they make it so that it stays in?... The whole thing has NOT FALLEN APART but could it if I keep using it? I shall have to be extra careful! Feeling a bit disappointed with it. Perhaps other makes of hand lens are better made? I believed the Opticron lens to be 'mid-range'.
