L-BCC027 12.7 mm Dia. Double-Concave Lens; EFL=-12.5mm Uncoated
The L-BCC027 is a 12.7 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, featuring a negative focal length (EFL) of -12.5mm, making it suitable for applications that require light convergence.
The lens's geometry includes an edge thickness of 5.07mm and a center thickness of 2.5mm, ensuring robustness and precision. The radii of curvature for this lens are R1=-13.73260896 and R2=13.73260896, which are symmetrically placed to provide a double-concave effect. The lens's inner and outer radii are both zero, indicating a uniform curvature throughout.
The L-BCC027 is made 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 work with a wavelength of 587.6nm, making it suitable for a wide range of applications.
Notably, this lens is uncoated, meaning it does not have any additional layers to enhance its optical properties. However, this does not affect its performance in many applications, and it can be easily customized with various coatings based on specific requirements.
