AL50100-B 50 mm Dia. S-LAH64 High-Precision; CNC Polished Aspheric Lenses; EFL=100 mm; NA=0.24 AR 650-1050nm
The AL50100-B is a high-precision aspheric lens offered by Thorlabs, a leading vendor in the optical industry. This lens, designed with a 50 mm diameter, is part of the S-LAH64 series, known for its superior optical performance and versatility.
The lens is made from n-BK7 Schott, a high-quality optical glass, and features an effective focal length (EFL) of 100 mm. The high numerical aperture (NA) of 0.24 enhances its light-gathering capability, making it suitable for a wide range of applications.
The aspheric design of the lens, characterized by its non-spherical surface, helps to reduce spherical aberration, a common issue in optical systems. This results in improved image quality and increased efficiency. The lens's geometry includes a center thickness of 10 mm and an edge thickness of 3.8 mm, contributing to its robustness and durability.
The lens is coated with a broadband anti-reflection (AR) coating, optimized for the 650-1050 nm range. This coating reduces surface reflections, thereby increasing transmission and minimizing losses. The coating is applied to both the front and back surfaces of the lens.
