L-PCX149 18 mm Dia. Plano-Convex Lens; EFL=35mm Uncoated
The L-PCX149 is a Plano-Convex lens with a diameter of 18 mm, making it suitable for a wide range of optical applications. This lens is characterized by its EFL (Effective Focal Length) of 35mm, which is a crucial parameter in determining the lens's magnification and field of view. The lens is uncoated, which means it does not have any anti-reflective or other surface coatings.
The lens's geometry is another key feature. It has a thickness of 1.5 mm at the edge and 3.9 mm at the center. The inner radius is 0, while the outer radius is also 0, indicating a symmetrical design. The radius of curvature (R1) is 18.088 mm, and the back focal length (BFL) is 32.55 mm.
The lens is made from N-BK7 Schott, a high-quality optical glass known for its excellent optical properties. The wavelength of 587.6 nm suggests that this lens is designed for use in the visible light spectrum.
