88-740 25.4mm Dia. x 50.8mm FL; VIS-EXT Coated Plano-Convex Lens VIS-EXT 350-700nm
The 88-740 is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens boasts a base shape of a circle and is designed for use in the visible light spectrum, specifically between 350-700nm. The lens has a diameter of 25.4mm and a focal length of 50.8mm, making it a versatile choice for various 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 and precise optical performance. The lens's geometry includes a thickness of 1.72mm at the edge and 5mm at the center, contributing to its robust construction.
The 88-740 lens features VIS-EXT coating on both the front and back surfaces. This coating enhances the lens's performance in the visible light spectrum, improving its transmission and reducing unwanted reflections. The coating also provides protection against environmental factors, ensuring the longevity of the lens.
