L-BCX087 18 mm Dia. Double-Convex Lens; EFL=27mm Uncoated

The L-BCX087 is a spherical lens with a base shape of circular and a double-convex design, sourced from the reputable vendor Ross Optical. This lens boasts a diameter of 18 mm and a center thickness of 5.5 mm, with an edge thickness of 2.4 mm, providing a robust structure suitable for various applications.

The lens has an effective focal length (EFL) of 27 mm, making it ideal for systems that require a longer focal length. The radii of curvature for the first and second surfaces are 26.94 mm and -26.94 mm, respectively, indicating a strongly converging lens. The lens does not have any coating, which may be suitable for applications where coating is not required or preferred.

The lens is made of n-BK7 Schott material, a high-quality borosilicate glass known for its excellent optical properties, including a high Abbe number and low dispersion. This material is widely used in various optical applications, such as lasers, beam expanders, and imaging systems.

The lens is designed to operate at a wavelength of 587.6 nm, making it suitable for applications that use this wavelength, such as sodium vapor lamps. The lens is uncoated, which may be beneficial in applications where anti-reflection coatings are not desired or necessary.
