L-BCX136 25.4 mm Dia. Double-Convex Lens; EFL=200mm Uncoated

The L-BCX136 is a 25.4 mm diameter Double-Convex lens, a type of spherical lens, sourced from Ross Optical. This lens is designed with a base shape that is circular, adding to its versatility in various optical applications.

The lens has an effective focal length (EFL) of 200mm, making it suitable for use in systems that require a longer focal length. The EFL is a critical parameter in lens selection, as it directly influences the magnification and field of view of the optical system.

The geometry of the lens includes a thickness of 3mm at the edge and 3.78mm at the center. The radii of curvature for the first and second surfaces are 206.07mm and -206.07mm respectively. The inner and outer radii are both zero, indicating that this lens is a simple double-convex lens without any additional features such as threads or flanges.

The lens is made from N-BK7 Schott, a popular optical glass known for its excellent optical properties and high damage threshold. This material is widely used in various optical applications, including laser systems, imaging systems, and beam delivery systems.

The lens is uncoated, meaning it does not have any anti-reflective coatings. While coatings can enhance the performance of a lens by reducing reflections and increasing transmission, an uncoated lens can be advantageous in certain applications where the simplicity and cost-effectiveness are prioritized.

The lens is currently in stock and can be purchased directly from the vendor's website. Detailed specifications and purchasing information can be found at the provided weblink.
