L-BCX035 9 mm Dia. Double-Convex Lens; EFL=27mm Uncoated

The L-BCX035 is a 9 mm diameter double-convex lens, sourced from the reputable optical vendor, Ross Optical. This lens is a spherical type, specifically designed with a convex-convex base shape, ensuring a high degree of focusing power.

The lens's geometry is meticulously crafted, with a thickness edge of 2 mm and a center thickness of 2.74 mm. The effective focal length (EFL) is 27 mm, making it suitable for a wide range of optical applications. The first radius of curvature (R1) is 27.43 mm, while the second radius (R2) is -27.43 mm, indicating the double-convex nature of the lens.

The lens is made from the high-quality material, n-bk7 schott, a borosilicate glass known for its excellent optical properties. It is designed to work with a wavelength of 587.6 nm, making it suitable for use in various optical systems.

Notably, this lens is uncoated, meaning it does not have any anti-reflective or other coatings applied to its surfaces. This may result in increased reflection at the air-glass interfaces, but it also means the lens is more cost-effective and versatile, as coatings can be added later according to specific application requirements.
