Meets the listed specifications. - All the specs are right. Glass quality is good. Faintest bit of "Window Glass" iron-green to the glass, but zero problems for my application. The size diameter micrometers exactly at 38mm as listed. I wanted objective lenses for a diy FPV headset like project, and wanted something better than plastic for the eyepieces. The edge grinding is even, and has no major chips etc. If what I'm building works out, I'm going to buy more. Review: Nice DIY Part - I used these with some 3D-printed stereoscopes, and they work wonderfully! They have a high quality of construction, consistent size (important for fitting into oculars), and a nice finish. Great part for your DIY project! ## Features - DOUBLE CONVEX || Highly polished, double convex lens - SPHERICAL || Lens measures 1.5" (38mm) in diameter - 50MM FOCAL LENGTH || Converging lens with a 50mm focal length - OPTICALLY WORKED GLASS || Made of high quality, optically worked glass.
