L-BCX183 38.1 mm Dia. Double-Convex Lens; EFL=200mm Uncoated

The L-BCX183 is a high-quality double-convex lens, part of Ross Optical's extensive catalog of optical elements. This lens, with a diameter of 38.1 mm, is designed for use in a wide range of optical applications, thanks to its versatile specifications.

The lens is spherical in shape, featuring a base shape that is circular. This spherical geometry is characterized by an inner radius of 0 and an outer radius of 0, indicating a symmetrical design. The lens's thickness at the edge is 3 mm, while the center thickness measures 4.76 mm, providing a solid and robust structure.

The L-BCX183 has an effective focal length (EFL) of 200mm, making it suitable for applications that require a longer focal length. The curvature of the lens is defined by two radii: r1, which is 205.91, and r2, which is -205.91. This design allows for a balanced distribution of light across the lens, enhancing its performance in various applications.

The lens is made from n-bk7 Schott, a high-grade optical material known for its excellent optical properties. This material is particularly suitable for use in the visible spectrum, with a wavelength of 587.6 nm.

Notably, this lens is uncoated. While coatings can enhance the performance of lenses by reducing reflections, increasing transmission, or providing other benefits, an uncoated lens can be advantageous in certain applications where specific coating properties are not required.
