10x De-Luxe Achromat loupe/comparator brand_Nikon the rear cover support pinWell, I don't know who made this loupe, but it's pretty nice: it's a clean 10x achromat with excellent sharpness, and it includes two comparator discs if you're planning to use it as a pocket comparator. It's an excellent loupe, with a transparent skirt that makes it suitable for reflective or transmissive materials. Includes case.
