L-PCX355 76.2 mm Dia. Plano-Convex Lens; EFL=200mm Uncoated

The L-PCX355 is a Plano-Convex lens, a type of spherical lens, sourced from Ross Optical. It boasts a diameter of 76.2 mm and a thickness at the edge of 3 mm, while the center thickness is 10.27 mm. The Effective Focal Length (EFL) of this lens is 200mm, making it suitable for a variety of optical applications.

The lens is made from N-BK7 Schott, a popular optical glass due to its excellent optical properties and high Abbe number. The Abbe number, a measure of the material's dispersion, is not provided in the item data, but N-BK7 Schott typically has an Abbe number of approximately 64.2.

The lens's inner radius is 0, indicating that it is a meniscus lens, and the outer radius is also 0, suggesting that the lens is symmetrical. The first radius of curvature (R1) is 103.36 mm, and the back focal length (BFL) is 193.23 mm.

The item data does not specify the wavelength for which the lens is designed, but it does mention 587.6 nm as a reference wavelength. This could suggest that the lens is designed for use in the visible spectrum, but without further information, this is only a speculation.

The lens does not appear to have any coating, as the coating field in the item data is empty. This could mean that the lens is uncoated, or it could simply mean that the coating information was not provided.
