L-BCX085 18 mm Dia. Double-Convex Lens; EFL=20mm Uncoated

The L-BCX085 is a spherical lens with a base shape of circular, sourced from the reputable vendor Ross Optical. This lens is a double-convex type, characterized by its convex-convex geometry, making it an ideal choice for a wide range of optical applications.

The lens has a diameter of 18 mm and a thickness edge of 1.5 mm, ensuring durability and robustness. The center thickness is 5.9 mm, providing a substantial base for secure mounting and alignment. The effective focal length (EFL) of this lens is 20 mm, making it suitable for applications that require a moderate focal length.

The L-BCX085 is made from n-bk7 Schott material, a high-quality optical glass known for its excellent transmittance and low auto-fluorescence. This material is ideal for applications that require high light transmission and low background noise. The lens is designed to work with a wavelength of 587.6 nm, ensuring optimal performance in visible light applications.

Please note that this lens is uncoated. While uncoated lenses can be cost-effective, they may be more susceptible to surface reflections and scattering, which can affect image quality. However, this can be mitigated with the use of anti-reflective coatings or other optical treatments.
