The 84-225 is a Plano-Convex Spherical Lens, sourced from the reputable vendor Edmund Optics. This lens boasts a 9.0mm diameter and a focal length of 36.0mm, making it suitable for a wide range of optical applications. The lens is crafted from the high-quality material n-BK7 Schott, ensuring durability and reliability.
The lens features a V-Coat 1550 coating on both the front and back surfaces, specifically designed for laser applications at a wavelength of 1550nm. This coating enhances the lens' performance by reducing reflection and increasing transmission, thereby improving the overall efficiency of the optical system.
The geometry of the lens is meticulously designed, with a thickness of 1.75mm at the edge and 2.3mm at the center. The lens' effective focal length (EFL) is 36.0mm, and the radius of curvature (R1) is 18.61mm. The back focal length (BFL) is 34.48mm, and both the inner and outer radii are 0mm.
