The 38-613-INK is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens boasts a diameter of 35.0mm and a focal length of 70.0mm, making it suitable for a wide range of optical applications. The lens is made from the high-quality material n-BK7 Schott, ensuring excellent optical performance.
The lens features a YAG-BBAR coating on both the front and back surfaces. This coating, specifically designed for the wavelength range of 500-1100nm, enhances the lens's performance by reducing reflection and increasing transmission. The coating is applied as an inked finish, ensuring durability and longevity.
The geometry of the lens is also noteworthy. The edge thickness measures 1.49mm, while the center thickness is 6mm. The lens's inner radius is 0mm, and the outer radius is also 0mm, indicating a uniform curvature. The back focal length (BFL) is 66.04mm, and the effective focal length (EFL) is 70mm.
