Review: 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: El lente es pequeño y tiene gran aumento. Me funcionó muy bien para mi proyecto casero de óptica. ## Features - Highly polished glass lens - Double Convex - 50mm focal length - 38mm diameter - Ground edges ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B01F9KXRX2 | | Batteries Required? | No | | Batteries included? | No | | Best Sellers Rank | 280,582 in Business, Industry & Science ( See Top 100 in Business, Industry & Science ) 313 in Lab Microscope Slides | | Customer Reviews | 4.3 4.3 out of 5 stars (54) | | Date First Available | 17 May 2016 | | Item Package Quantity | 1 | | Item Weight | 18 g | | Item model number | PH0534ACV | | Manufacturer | Eisco | | Material | ABS_(Acrylonitrile_Butadiene_Styrene), PE_(Polyethylene) | | Part number | PH0534ACV | | Product Dimensions | 3.05 x 3.05 x 0.25 cm; 18 g | ## Images ![Labs Glass Lenses - Double Convex, 38mm Diameter, 50mm Focal Length - Image 1](https://m.media-amazon.com/images/I/71tOkPvRp4L.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by A***K on 8 August 2025* All the specs are right.
