This is a 49-168 Plano-Convex Lens, a high-quality optical component sourced from Edmund Optics. The lens boasts a 3.0mm diameter and a focal length of 4.5mm, making it suitable for a wide range of applications.
The lens is made from n-lasf44 Schott, a material known for its excellent optical properties. It is designed to work optimally with visible light, specifically within the wavelength range of 425-675nm.
The lens features a standard curve coating on both the front and back surfaces, denoted as 'edm vis-0 std curve'. This coating enhances the lens's performance by reducing surface reflections and improving transmission, thereby increasing the overall efficiency of the optical system.
The geometry of the lens is characterized by its edge thickness of 1.47mm and center thickness of 1.8mm. The lens's inner and outer radii are both zero, indicating a plano-convex shape. The radius of curvature (R1) is 3.62mm, and the back focal length (BFL) is 3.5mm.
