L-PCX220 30 mm Dia. Plano-Convex Lens; EFL=200mm Uncoated

The L-PCX220 is a Plano-Convex lens with a diameter of 30 mm, sourced from the renowned optical component vendor, Ross Optical. This lens is specifically designed for use in a variety of optical systems, boasting an effective focal length (EFL) of 200mm. The Plano-Convex design, characterized by a flat surface on one side and a curved surface on the other, is a popular choice due to its ability to minimize spherical aberration.

The lens's geometry includes a thickness of 2 mm at the edge and 3.1 mm at the center, contributing to its robust construction. The inner and outer radii are both 0, indicating a symmetrical curvature. The radius of curvature (R1) is 103.36 mm, and the back focal length (BFL) is 198.7 mm, providing a clear understanding of the lens's optical properties.

The lens is made from N-BK7 Schott, a popular optical glass due to its excellent optical properties and high Abbe number. This makes it an ideal choice for applications that require high optical performance and precision. The lens is uncoated, meaning it does not have any additional layers to enhance its optical properties or protect it from environmental factors. However, uncoated lenses can be more susceptible to surface reflections and scratches.

This lens is designed to work with a wavelength of 587.6 nm, making it suitable for a wide range of applications. The lens's spherical shape ensures a consistent curvature, which is crucial for maintaining image quality in optical systems.
