L-BCX088 18 mm Dia. Double-Convex Lens; EFL=35mm Uncoated

The L-BCX088 is a double-convex lens with an 18 mm diameter, sourced from Ross Optical. This lens is a spherical type, featuring a base shape that is circular. The lens's geometry includes a thickness edge of 1.5 mm and a thickness center of 3.8 mm, with an effective focal length (EFL) of 35 mm. The radii of curvature for the first and second surfaces are 35.52 mm and -35.52 mm, respectively. The lens does not have an inner or outer radius.

The lens is made of n-BK7 Schott material, a popular choice for its high refractive index and low dispersion. It is designed to operate at a wavelength of 587.6 nm. The lens's coating is listed as 'uncoated' in the provided data, meaning it does not have any additional anti-reflective or protective coatings.

This lens is a Convex-Convex type, which means it has two convex surfaces. This design is often used in applications where a high degree of focusing is required. The lens's uncoated state makes it suitable for use in applications where a natural chromatic aberration is acceptable or desirable.
