<p>[QUOTE=&quot;physics-fan3.14, post: 6271070, member: 19165&quot;]There are a few recommendations I have for loupes. </p><p><br /></p><p>The first, absolutely make sure you buy a Hastings Triplet. This refers to the type of lens - it has three different pieces of glass layered and designed to sandwich together. This is key, because it helps to reduce distortion under high magnification. Don&#039;t buy a loupe that is not a triplet. </p><p><br /></p><p>Second - forget the &quot;lighted&quot; loupes. They are usually not as high quality, and harder to use. A good desk lamp is important. </p><p><br /></p><p>Third - a good loupe is not going to be cheap. You&#039;re probably looking at $30 for an entry level, up to $50-$60 for high quality. Don&#039;t skimp on the optics, because the difference between a low quality plastic lens and a high quality glass is really huge. </p><p><br /></p><p>Fourth - don&#039;t go overboard on magnification. The magnification you get should be based on what you want it for: if you&#039;re looking for just a bit of magnification to see the coin a bit better, because your eyes are getting old, 2 or 3x is sufficient. If you&#039;re looking for surface problems, 5x is probably enough. If you&#039;re looking for varieties, 10x is enough. I don&#039;t really recommend anything higher than 10x, there is just no need for it. </p><p><br /></p><p>Fifth - there is a difference between manufacturers. You want to go with a high quality optics company. The top three loupe manufacturers I&#039;d say are Bausch &amp; Lomb, Eschenbach, and Zeiss. </p><p><br /></p><p>Sixth - if you&#039;re ordering online, make sure there&#039;s a return policy. Different loupes will fit your hand and eyes better; you need the chance to try it out before you commit to buy it.[/QUOTE]</p><p><br /></p>
