LSB03506 6 mm Dia. Sapphire Ball Lenses Uncoated

The LSB03506 is a ball lens with a 6 mm diameter, sourced from Knight Optical. This lens is specifically designed for use in the ultraviolet, visible, and near-infrared spectrum, making it a versatile choice for a wide range of optical applications.

The lens boasts a focal length of 3.45 mm, as indicated by its effective focal length (EFL). This EFL is a crucial factor in determining the lens's performance in a given system, as it directly influences the convergence or divergence of light rays passing through the lens.

The lens is made from sapphire, a material with the chemical formula Al2O3. This material is renowned for its exceptional hardness, making it highly resistant to scratching and other forms of damage. Additionally, sapphire is transparent across a broad spectral range, from the ultraviolet to the near-infrared, making it an ideal choice for many optical systems.

Notably, this particular lens is uncoated. While coatings can enhance the performance of optical elements in various ways, such as by reducing reflective losses or protecting against environmental hazards, an uncoated lens can offer advantages in certain situations. For instance, an uncoated lens may be preferred when working with broadband light sources, as it can provide a more uniform transmission profile across the entire spectrum.
