88-739 25.4mm Dia. x 38.1mm FL; VIS-EXT Coated Plano-Convex Lens VIS-EXT 350-700nm
The 88-739 is a Plano-Convex lens, a type of spherical lens with a single curved surface and a flat surface. This lens, sourced from Edmund Optics, boasts a diameter of 25.4mm and a focal length of 38.1mm, making it suitable for a wide range of optical applications.
The lens is made from n-BK7 Schott, a high-quality optical glass known for its excellent transparency and low dispersion. This material ensures that the lens provides clear, distortion-free images across the visible spectrum, from 350 to 700nm.
The 88-739 features a VIS-EXT coating on both the front and back surfaces. This coating, specifically designed for the visible spectrum, enhances the lens's transmission capabilities and reduces surface reflections. The result is a lens that maximizes light transmission while minimizing unwanted glare and ghosting.
The lens has a center thickness of 7mm and an edge thickness of 2.36mm, providing a robust and durable structure. Despite its robustness, the lens remains lightweight and easy to handle, making it a versatile choice for various optical systems.
