88-634 5.0mm Dia. x 20.0mm FL; VIS-EXT Coated Plano-Convex Lens VIS-EXT 350-700nm
The 88-634 is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. It boasts a circular base shape with a diameter of 5.0mm and a thickness of 1.19mm at the edge, transitioning to 1.5mm at the center. The lens has an effective focal length (EFL) of 20.0mm, making it suitable for a variety 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 makes the lens particularly suitable for applications that require high image quality and precise light control.
The 88-634 is coated with EDM VIS-EXT, a broadband anti-reflection coating designed for use in the visible spectrum, specifically between 350-700nm. This coating reduces surface reflections, enhancing the lens's light transmission capabilities and improving overall system performance.
The lens's geometry includes an inner radius of 0mm and an outer radius of 0mm, indicating a simple, straightforward design. This, coupled with its compact size and robust construction, makes the 88-634 a versatile and reliable choice for a wide range of optical systems.
