L-PCC033 18 mm Dia. Plano-Concave Lens; EFL=-35mm Uncoated

The L-PCC033 is a plano-concave lens with a diameter of 18 mm, sourced from the reputable optical vendor, Ross Optical. This lens is designed for use in various optical systems, featuring a negative focal length (EFL) of -35 mm, making it suitable for applications that require light convergence.

The lens's geometry is characterized by its base shape, which is circular, and its thickness at the center, measuring 1.5 mm. The inner and outer radii are both zero, indicating a plano-concave design. The radius of curvature (R1) is -18.088 mm, which contributes to the lens's negative focal length.

The L-PCC033 lens is made from the high-quality material n-BK7 Schott. This material is known for its excellent optical properties, including a high Abbe number and low dispersion, making it ideal for a wide range of optical applications. The lens is designed to work with a wavelength of 587.6 nm.

Please note that this lens is uncoated. Coatings are often applied to lenses to enhance their optical performance by reducing reflection, increasing transmission, or providing other desirable optical properties. However, this lens is designed to function without a coating, making it a cost-effective option for applications where coated lenses are not required.
