{"product_id":"jewellers-loupe-triplet-21mm","title":"Jeweller's loupe, triplet, 21 mm","description":"\u003cp\u003eYou drilled the hole. Is the edge clean, or did the bit tear out on the way through? At arm's length every hole looks fine. That is what this is for.\u003c\/p\u003e\n\n\u003ch2\u003eTriplet, and why that word matters\u003c\/h2\u003e\n\u003cp\u003eA cheap magnifier is one piece of glass. Look through it and the edges of the picture bend, and every hard edge picks up a coloured fringe — red on one side, blue on the other. On a stone or a hallmark that fringe is exactly the detail you were trying to see.\u003c\/p\u003e\n\u003cp\u003eA triplet is three lenses cemented into one stack, arranged so those two faults cancel. The picture stays flat to the rim and the colours stay where they belong. It is the reason a jeweller's loupe costs more than a plastic magnifier, and the only reason.\u003c\/p\u003e\n\u003cp\u003eThe lens is 21 mm. Chrome-plated body, folds into its own shell, comes in a hard case.\u003c\/p\u003e\n\n\u003ch2\u003eWhich magnification, and please read this part\u003c\/h2\u003e\n\u003cp\u003eMore is not better. Magnification costs you working distance and field of view, and both go fast.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e10x\u003c\/strong\u003e is the one most bench work actually uses. You hold it a couple of centimetres off the work, you can see a whole watch dial or the full length of a drilled hole at once, and your hand can shake a little without the picture running away. If you buy one loupe, buy this one.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e20x\u003c\/strong\u003e is the middle. Good for solder joints, jewel settings and checking a thread.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e30x\u003c\/strong\u003e sits almost on the surface and shows you a field about the size of a grain of rice. It is for hallmarks, inclusions in a stone and the tip of a 0.4 mm drill bit. It is not a general-purpose loupe and it will frustrate you as one.\u003c\/p\u003e\n\n\u003ch2\u003eWhat it is not\u003c\/h2\u003e\n\u003cp\u003eThere is no light in it. You hold it to the eye and bring the work to it, and you need a lamp.\u003c\/p\u003e\n\u003cp\u003eIt is not a microscope. For hours of soldering under magnification you want a stereo microscope on a stand, not something held in the eye socket.\u003c\/p\u003e\n\n\u003ch2\u003eShipping and returns\u003c\/h2\u003e\n\u003cp\u003eFree shipping in the US, 5 to 15 business days. Returns accepted for 30 days from delivery.
