L-PCX200 145 mm Dia. Plano-Convex Lens; EFL=250mm Uncoated
The L-PCX200 is a Plano-Convex lens with a diameter of 145 mm, sourced from the reputable optical vendor, Ross Optical. This lens is a spherical element, designed with a base shape of a circle, and it is uncoated. The lens's geometry is defined by its diameter, thickness at the edge (3.7 mm), and thickness at the center (25.9 mm). The Effective Focal Length (EFL) is 250 mm, making it suitable for various optical applications.
The lens's inner radius is 0 mm, and the outer radius is also 0 mm, indicating a uniform curvature. The first radius of curvature (R1) is 129.2 mm, and the back focal length (BFL) is 233.86 mm. The lens is made of N-BK7 Schott material, a common choice for its high refractive index and low dispersion.
This lens is designed to work with a wavelength of 587.6 nm, typically used in visible light spectrum applications. The lens's coating is absent, which means it is uncoated. This could lead to higher scattering and lower transmission compared to coated lenses, but it may also be beneficial in specific applications where no coating is desired.
