LBB0304 4 mm Dia. N-BK7 Ball Lenses Uncoated

The LBB0304 is a 4 mm diameter Ball Lens, a type of optical component known for its spherical shape, designed to focus or collimate light. This particular model is sourced from Knight Optical, a reputable vendor in the field of optical components.

The lens is made of N-BK7, a high-quality optical glass from Schott, renowned for its excellent optical properties and versatility across a wide range of applications. The N-BK7 material ensures high transmission in the UV, visible, and near-infrared regions, making it a popular choice for many optical systems.

The LBB0304 has an effective focal length (EFL) of 2.93 mm, a critical parameter that determines the lens's focusing power. This EFL suggests that the lens will provide a relatively tight focus, ideal for applications that require concentrated light.

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 situations. For instance, uncoated lenses can be more cost-effective and are often more resistant to laser damage.
