This is a Plano-Convex Lens, a type of spherical lens, sourced from the renowned optical vendor, Edmund Optics. The lens boasts a diameter of 12.0mm and a focal length of 72.0mm, making it suitable for a wide range 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 ideal for use in laser applications, particularly at the wavelength of 1550nm.
The lens features a V-coat, a type of anti-reflective coating, on both the front and back surfaces. This coating is specifically designed for use with lasers at 1550nm, reducing surface reflections and improving transmission.
The lens has a thickness of 1.91mm at the edge and 2.4mm at the center. The inner and outer radii are 0mm, indicating a flat surface on the non-curved side of the lens. The back focal length is 70.42mm.
