L-PCX204 30 mm Dia. Plano-Convex Lens; EFL=40mm Uncoated
The L-PCX204 is a 30 mm diameter Plano-Convex lens, sourced from the renowned optical vendor, Ross Optical. This lens is specifically designed for use in optical systems that require a convex lens with a flat plane on one side. The lens is uncoated, which means it does not have any additional layers to protect the surface or modify its optical properties.
The lens's geometry is defined by a 30 mm diameter, with a thickness of 2 mm at the edge and 8.4 mm at the center. The Effective Focal Length (EFL) is 40 mm, which is the distance from the lens's center to the point where light rays converge or diverge. The lens's front radius (R1) is 20.672 mm, and the back focal length (BFL) is 34.61 mm. The lens's inner and outer radii are both 0, indicating that the lens is uniformly curved.
The lens is made of N-BK7 Schott, a popular optical glass due to its excellent optical properties and wide transparency range. The wavelength for this lens is 587.6 nm, which is in the visible light spectrum. The lens's shape is spherical, meaning it has the same curvature in all directions.
