LFB02500 2.5 mm Dia. Quartz Ball Lenses Uncoated

The LFB02500 is a 2.5 mm diameter ball lens, sourced from Knight Optical, designed for use in UV, visible, and NIR applications. This uncoated lens boasts a base shape of a perfect circle, ensuring excellent light transmission and minimal distortion.

The lens has an effective focal length (EFL) of 1.77 mm, making it suitable for a wide range of optical systems. The EFL is a critical parameter in lens selection, as it directly impacts the convergence or divergence of light rays passing through the lens.

The lens is crafted from quartz (SiO2), a high-quality optical material known for its excellent transparency across a broad spectrum, from ultraviolet to infrared wavelengths. This material choice ensures high-fidelity light transmission, making the LFB02500 a versatile option for various optical applications.

Notably, the lens is uncoated, meaning it does not have any additional layers to enhance its optical properties or protect it from environmental factors. While this may limit its use in certain harsh environments, it can be advantageous in applications where minimal reflection is required.
