LSB014025 2.5 mm Dia. Sapphire Ball Lenses Uncoated

The LSB014025 is a 2.5 mm diameter ball lens, specifically designed and manufactured by Knight Optical. This lens is a part of the Ball Lens category, which is a sub-type of the general Lens category. The base shape of this lens is circular, ensuring optimal light transmission and focusing capabilities.

The lens has a geometry that includes a diameter of 2.5 mm, an effective focal length (EFL) of 1.44, an inner radius of 0, and an outer radius of 0. The EFL is a critical parameter that determines the lens's ability to focus light. A higher EFL indicates a greater ability to focus light, making this lens suitable for various applications.

The lens is made of Sapphire (Al2O3), a high-quality material known for its excellent optical properties. The material ID for this lens is al2o3 mal-1972-n-o. Sapphire is a durable and scratch-resistant material, making it ideal for applications that require high precision and longevity.

The lens is designed to operate at a wavelength of 587.6 nm. This wavelength is within the visible light spectrum, indicating that this lens is suitable for applications that involve visible light.

The lens does not have any coating, which means it is uncoated. While coatings can enhance the optical performance of a lens, an uncoated lens can be suitable for certain applications, especially where cost and simplicity are priorities.
