L-BCX059 12.5 mm Dia. Double-Convex Lens; EFL=35mm Uncoated

The L-BCX059 is a spherical lens with a base shape of a circle, sourced from the reputable vendor Ross Optical. This lens is a double-convex type, meaning it has two convex surfaces, which is indicated by the "Sub Type" being "Spherical Lens (Convex-Convex)".

The lens has a diameter of 12.5 mm and a thickness at the edge of 1.5 mm, while the center thickness is 2.6 mm. The effective focal length (EFL) of this lens is 35 mm. The radii of curvature for the first and second surfaces are 35.73 mm and -35.73 mm respectively, indicating that the lens is symmetrical. The inner and outer radii are both 0, suggesting that the lens has a uniform thickness.

The lens is made of material with the ID "n-bk7 schott", which is a common type of optical glass known for its excellent optical properties. The wavelength for this lens is 587.6 nm. The lens does not have any coating, as indicated by the empty "coating" field in the item data.

This lens is a versatile optical component, suitable for a wide range of applications that require a double-convex lens. Its specifications make it an ideal choice for applications that require a lens with a high degree of symmetry and a long focal length.
