88-689 12.7mm Dia. x 31.8mm FL; VIS-EXT Coated Plano-Convex Lens VIS-EXT 350-700nm

This is a 12.7mm diameter, plano-convex lens with a focal length of 31.8mm, designed for use within the visible light spectrum (350-700nm). The lens is sourced from Edmund Optics, a reputable vendor known for their high-quality optical components.

The lens is made from n-BK7 Schott, a popular optical glass due to its excellent optical properties and versatility. The plano-convex geometry, where one side is flat and the other is curved, is a common design for lenses used in various applications.

The lens features a VIS-EXT coating on both the front and back surfaces. This coating is specifically designed to enhance transmission in the visible spectrum, making it ideal for applications where high light transmission is required.

The lens has a center thickness of 3mm and an edge thickness of 1.72mm. The inner and outer radii are not specified, indicating that they are not a significant factor in this lens's design or application.
