AL3026-A 30 mm Dia. S-LAH64 High-Precision; CNC Polished Aspheric Lenses; EFL=26 mm; NA=0.52 AR 350-700nm
The AL3026-A 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 lens's geometry is another notable feature. It has an inner radius of 0 mm, an outer radius of 0 mm, and a thickness at the edge of 3.9 mm. The thickness at the center is 9.7 mm, providing robustness and durability. The lens's shape is aspheric, which is advantageous as it minimizes spherical aberration, a common issue in optical systems.
The lens's surface is CNC polished, ensuring superior optical quality. It is coated with a broadband anti-reflective coating (AR 350-700nm), which reduces unwanted reflections and increases transmission, enhancing the overall performance of the lens.
