L-BCC109 50 mm Dia. Double-Concave Lens; EFL=-125mm Uncoated
The L-BCC109 is a 50 mm diameter Double-Concave Spherical Lens, sourced from the renowned optical vendor, Ross Optical. This lens is designed with a base shape of a circle and features a significant double-concave geometry, making it an ideal choice for specific optical applications.
The lens has a center thickness of 2.5 mm and an edge thickness of 7.3 mm, providing a robust structure while maintaining a sleek profile. The effective focal length (EFL) of this lens is -125 mm, indicating its diverging nature, which is further emphasized by its radii of curvature, R1 (-130.4318727) and R2 (130.4318727).
The L-BCC109 is crafted from the high-quality material, N-BK7 Schott, a borosilicate crown glass known for its excellent optical properties and durability. The lens is designed to operate at a wavelength of 587.6 nm.
Notably, this lens is uncoated, offering users the flexibility to apply their preferred coating based on their specific application requirements. However, it's crucial to note that uncoated lenses may have higher reflectivity and lower transmission compared to coated ones.
