L-PCX250 38.1 mm Dia. Plano-Convex Lens; EFL=200mm Uncoated
The L-PCX250 is a Plano-Convex lens with a diameter of 38.1 mm, making it suitable for a wide range of optical applications. This lens is sourced from Ross Optical, a reputable vendor known for their high-quality optical elements. The lens features an effective focal length (EFL) of 200mm, which is a common choice for many optical systems due to its versatility.
The lens is made from N-BK7 Schott, a popular optical glass due to its excellent optical properties and high Abbe number. This material ensures high transmittance across a wide spectrum, making it suitable for various wavelengths. However, it's important to note that the lens is uncoated, which means it may not perform optimally in environments with high levels of light scattering or where anti-reflective properties are required.
The geometry of the lens includes a thickness of 3mm at the edge and 4.77mm at the center. The inner radius is 0, while the outer radius is also 0, indicating a flat surface on one side and a curved surface on the other. The radius of curvature (R1) is 103.36mm, and the back focal length (BFL) is 196.85mm.
