L-BCX019 15 mm Dia. Double-Convex Lens; EFL=20mm Uncoated

The L-BCX019 is a 15 mm diameter double-convex lens, sourced from the renowned optical vendor, Ross Optical. This lens is a prime example of a Spherical Lens, specifically a Convex-Convex type, with a circular base shape.

The lens's geometry is meticulously designed, with a thickness edge of 2 mm and a thickness center of 4.9 mm. The Effective Focal Length (EFL) is 20 mm, making it suitable for a wide range of optical applications. The first radius of curvature (R1) is 19.8 mm, while the second radius (R2) is -19.8 mm, indicating the double-convex nature of the lens.

The lens is crafted from the high-quality material, N-BK7 Schott, a borosilicate glass known for its excellent optical properties. The wavelength of 587.6 nm is ideal for visible light applications.

Notably, this lens is uncoated, offering users the flexibility to apply their preferred coating based on their specific application requirements. The lens's uncoated state also means it can be easily integrated into existing optical systems without the need for additional coating compatibility considerations.
