#This means their products come with a premium attached for the consistent quality items they produce. A 10X loupe from either is likely to cost anywhere between $60 – $100, although pre-owned loupes are often available even on sites like eBay and Amazon.
Into the bargain, what magnification loupe do jewelers use?
The most common and preferred magnification level for jewelers' loupes would be a 10x magnification loupe. Jewelers loupes with more magnification power are available, but for most jeweler loupes, 10x magnification will be the preferred power you are looking for.
Just, how do I choose a jeweler's loupe? A proper loupe for gemology or jewelry has to be a ten-power (10x) triplet – three lenses fused together to eliminate distortion at the edges and color fringing. You know those big magnifying glasses you used to see elderly people use?
Regardless, how do I choose an eye loupe?
In general, you should choose the lowest possible magnification for your needs. It's simple: the lower the magnification, the greater your field of vision and depth of field. At the same time, the longer the working distance, the greater the field of view.
What is a jewelry loop?
A loupe is a small magnifying glass used by jewelers. The glass measures approximately half an inch in diameter, ranges from ten to twenty times magnification, and usually folds in on itself for easy carrying.
In general, a 20x objective maps 0.5 microns (of the specimen on the slide) to a single pixel on the camera. The final magnification is obtained by dividing the display pixel size (in microns) by the pixel mapping. For a 70" HD TV (1920x1080), the pixel size is about 0.8mm (800 microns).
For example, if you're looking at a 3-diopter lens, it's magnification = ¾ + 1... or . ... Objects viewed under a 3 diopter lens will appear 175% bigger than normal. A 5-diopter lens = 5/4 + 1... or 1.25 + 1 = 2.25x. Objects viewed under a 5 diopter lens will appear 225% bigger than normal.
Jeweller's Loupes are an essential workbench item for jewellers working with smaller or more intricate jewellery pieces. A small magnification device, loupes can be held near objects to give you a magnified view of what you're working with.
