L-PCX270 45 mm Dia. Plano-Convex Lens; EFL=500mm Uncoated

The L-PCX270 is a Plano-Convex lens with a diameter of 45 mm, sourced from the renowned optical vendor, Ross Optical. This lens is designed for use in a wide range of optical applications, thanks to its impressive focal length of 500 mm and its uncoated surface.

The lens's geometry is characterized by its base shape, which is circular, and its thickness. The edge thickness is 2 mm, while the center thickness is 3 mm. The lens's effective focal length (EFL) is 500 mm, making it suitable for applications that require a long focal length. The lens's first radius of curvature (R1) is 258.4 mm, and the back focal length (BFL) is 499.84 mm. The lens's inner and outer radii are both 0 mm, indicating a flat surface on one side and a curved surface on the other.

The lens is made from N-BK7 Schott, a high-quality optical glass known for its excellent optical properties. The lens is uncoated, meaning it does not have any anti-reflective or other coatings applied to its surface. This may make it more susceptible to environmental factors such as dust and moisture, but it can also make it more cost-effective.

The lens is designed to work with a wavelength of 587.6 nm, which is in the visible light spectrum. Its spherical shape ensures that light passing through it is focused to a single point, making it ideal for use in imaging and other applications where precise focus is required.
