L-BCX259 75 mm Dia. Double-Convex Lens; EFL=350mm Uncoated

The L-BCX259 is a 75 mm diameter Double-Convex lens, sourced from the renowned optical vendor, Ross Optical. This lens is a Spherical Lens of the Convex-Convex sub-type, featuring a Circular base shape. The lens is designed with a high level of precision, making it suitable for a wide range of optical applications.

The lens's geometry is defined by its diameter of 75 mm, with a center thickness of 7.4 mm and an edge thickness of 3.5 mm. The Effective Focal Length (EFL) of this lens is 350 mm, providing a substantial level of magnification. The first and second radii of the lens are 360.49 mm and -360.49 mm respectively, contributing to its Double-Convex shape. The Inner and Outer Radii are both 0, indicating a uniform curvature throughout the lens.

The L-BCX259 lens is made from the high-quality material, n-bk7 schott. This material is known for its excellent optical properties, making it a popular choice in the optical industry. The lens is designed to work with a wavelength of 587.6 nm, ensuring optimal performance in its intended application.

Notably, this lens does not come with any coating. Coatings are often applied to lenses to enhance their optical properties, such as reducing reflection or increasing transmission. However, the L-BCX259's uncoated status does not necessarily diminish its quality or usability. It is still a highly precise and reliable lens, suitable for various optical applications.

In conclusion, the L-BCX259 is a 75 mm diameter Double-Convex lens with an EFL of 350 mm, manufactured by Ross Optical. It is made from the high-quality material n-bk7 schott and is uncoated. This lens is a versatile and reliable choice for various optical applications.
