I am selling a like new Peak 4x anastigmatic loupe:


$39 shipped within continental USA.

Note: Official working distance is 54mm. But I measured it to be 16mm, from bottom lens to a flat paper, when focused. I think the official WD is measured differently, than my method.

This loupe was designed for viewing microfilm on light table, which may explain its short working distance. Image quality is very good.

I also measured the weight to be 164 grams, which is very close to the official 172 g number. Two lens caps probably make up that difference (note the bottom lens is a huge 58mm), I am guessing.

Edit: I have listed the loupe on eBay: http://www.ebay.com/itm/Peak-Anastigmat-Lupe-Loupe-4x-1990-4-microfilm-magnifier-inspection-lens-/152708640419
