L-BCC089 38.1 mm Dia. Double-Concave Lens; EFL=-200mm Uncoated
The L-BCC089 is a 38.1 mm diameter Double-Concave Spherical Lens, sourced from the renowned optical component vendor, Ross Optical. This lens is designed for use in systems where a negative focal length is required, with an Effective Focal Length (EFL) of -200mm.
The lens features a base shape of Circular geometry, with a thickness at the edge of 3.92mm and a center thickness of 2.5mm. The radii of curvature for this lens are R1=-207.3856624 and R2=207.3856624, indicating a symmetrical double-concave design. The Inner and Outer Radius are both 0, suggesting a uniform curvature throughout the lens.
The L-BCC089 is made from N-BK7 Schott material, a popular choice for its high refractive index and low dispersion. The wavelength for this lens is 587.6nm. Notably, this lens is uncoated, which may affect its performance in certain applications, particularly where high light transmission or resistance to environmental factors is required.
This lens is currently in stock and more information can be found on the Ross Optical website.
