4.5mm Diameter x 4.5mm FL Double-Convex Lens with Visible Light Coating
This 4.5mm diameter x 4.5mm focal length (FL) double-convex lens, sourced from Edmund Optics, is a high-quality optical component designed for use in a wide range of applications. The lens is made from n-lasf44 Schott material, ensuring durability and reliability.
The lens features a double-convex geometry, with a 6.58mm radius of curvature on both sides. This shape is ideal for applications requiring a wide field of view and low spherical aberration. The lens has a center thickness of 2.6mm and an edge thickness of 1.8mm, providing a balance between weight and optical performance.
The lens is coated with a standard visible light (VIS 0deg) coating on both the front and back surfaces. This coating enhances the lens's transmission in the visible light spectrum, making it suitable for use in applications such as imaging, machine vision, and beam shaping.
The lens has an effective focal length (EFL) of 4.5mm, which, combined with its diameter, results in a high numerical aperture (NA). This makes the lens ideal for use in high-resolution imaging applications.
