L-BCX223 20 mm Dia. Double-Convex Lens; EFL=40mm Uncoated
The L-BCX223 is a 20 mm diameter Double-Convex lens, sourced from the renowned optical vendor, Ross Optical. This lens is a Spherical Lens of the Convex-Convex subtype, featuring a Base Shape of Circular geometry.
The lens has a center thickness of 4.9 mm and an edge thickness of 2.4 mm, providing a robust structure. The Effective Focal Length (EFL) of this lens is 40mm, making it suitable for a wide range of optical applications.
The L-BCX223 is made from the high-quality material N-BK7 Schott, a borosilicate glass known for its excellent optical properties. The lens is designed to work with a wavelength of 587.6 nm, typically used in visible light spectrum applications.
Notably, this lens does not come with any coating, as indicated in the item data. Coatings are often applied to lenses to enhance their performance by reducing reflections, increasing transmission, or providing other benefits. However, the uncoated nature of the L-BCX223 may be advantageous in certain applications where specific coating properties are not required.
