LBB018025 2.5 mm Dia. N-BK7 Ball Lenses Uncoated

The LBB018025 is a 2.5 mm diameter Ball Lens, sourced from Knight Optical, a renowned vendor in the optical components industry. This lens, specifically made from N-BK7 Schott, is a prime example of high-quality optical components, designed to deliver reliable and efficient performance.

The Ball Lens, also known as a plano-convex lens, features a convex surface that is centrally rounded to a spherical shape. This geometry provides a wide field of view and minimal optical aberrations, making it suitable for a wide range of applications. The lens has an effective focal length (EFL) of 1.83, which is the distance from the center of the lens to the focal point, where light rays converge.

The LBB018025 is designed to operate at a wavelength of 587.6 nm, a common value in the visible light spectrum. This wavelength falls within the range of sensitivity for the human eye, making it suitable for applications that require high-visibility performance.

Notably, this Ball Lens is uncoated, meaning it does not have any additional layers to enhance its optical properties. While coatings can improve characteristics such as light transmission and resistance to environmental factors, an uncoated lens can be advantageous in certain applications where specific coating properties are not required.
