L-PCC046 25 mm Dia. Plano-Concave Lens; EFL=-25.4mm Uncoated

The L-PCC046 is a 25 mm diameter Plano-Concave lens, sourced from the renowned optical vendor, Ross Optical. This lens is a spherical element, featuring a base shape of a circle, designed to diverge light. The lens's geometry includes a center thickness of 1.2 mm, an effective focal length (EFL) of -25.4 mm, and a radius of curvature (R1) of -13.12672 mm. The lens's inner and outer radii are both zero, indicating a plano surface on one side and a concave surface on the other.

The lens is made from the high-quality material, N-BK7 Schott, a borosilicate crown glass known for its excellent optical properties, including a low coefficient of thermal expansion and high transmittance in the visible spectrum. The lens is designed to operate at a wavelength of 587.6 nm.

Notably, this lens is uncoated. Coatings are often applied to lenses to enhance their performance by reducing reflection, increasing transmission, or providing protection against environmental factors. However, this lens is in its bare form, offering the user the raw optical properties of the glass itself.

The lens's data is available on the Ross Optical website, and the link provided indicates that it is currently in stock, ensuring quick and efficient procurement for your optical needs.
