L-BCX171 38.1 mm Dia. Double-Convex Lens; EFL=38.1mm Uncoated

The L-BCX171 is a high-quality double-convex lens, part of the extensive catalog offered by Ross Optical. This lens, with a diameter of 38.1 mm, is designed for use in a wide range of optical applications, thanks to its robust construction and precise specifications.

The lens is spherical in shape, with a base shape of a circle. It features a double-convex design, meaning it has two convex surfaces. This design is often used to diverge or converge light rays, making it ideal for applications such as beam expansion, image reduction, or collimation.

The geometry of the L-BCX171 includes a thickness edge of 1.9 mm and a thickness center of 12.4 mm. The effective focal length (EFL) is 38.1 mm, which is the same as its diameter, indicating a relatively thin lens. The first radius of curvature (R1) is 37.14 mm, and the second radius of curvature (R2) is -37.14 mm, reflecting its double-convex design.

The lens is made from n-BK7 Schott, a high-grade optical glass known for its excellent transparency and low dispersion. This makes the L-BCX171 suitable for use in applications where high light transmission and minimal chromatic aberration are required.

The lens is uncoated, meaning it does not have any anti-reflective or other surface treatments. This may be suitable for applications where such coatings are not necessary or desirable. However, users should be aware that uncoated lenses can suffer from reduced light transmission and increased reflection, especially at larger angles of incidence.
