AL3026-C 30 mm Dia. S-LAH64 High-Precision; CNC Polished Aspheric Lenses; EFL=26 mm; NA=0.52 AR 1050-1700nm

The AL3026-C is a high-precision aspheric lens, meticulously crafted by Thorlabs. This lens boasts a 30 mm diameter and is constructed from S-LAH64, a material renowned for its exceptional optical properties. The lens is designed for use with a wavelength of 780 nm, making it suitable for a wide range of applications.

The lens features an effective focal length (EFL) of 26 mm, which is a crucial parameter in lens selection. The EFL determines the distance between the lens and the focal point, influencing the overall design and functionality of the optical system.

The aspheric design of the lens is a significant advantage. Unlike spherical lenses, aspheric lenses have a non-spherical surface, which reduces spherical aberration and improves optical performance. This makes the AL3026-C an excellent choice for applications requiring high image quality and precision.

The lens is also CNC polished, ensuring a smooth, high-quality surface finish. This process enhances the lens's light transmission capabilities and further contributes to its overall performance.

The lens is coated with Thorlabs' proprietary broadband anti-reflection coating, which is designed to reduce surface reflections and increase transmission in the 1050-1700 nm range. This coating improves the lens's performance in various applications, including near-infrared (NIR) imaging and spectroscopy.
