AL1512-A 15 mm Dia. S-LAH64 High-Precision; CNC Polished Aspheric Lenses; EFL=12 mm; NA=0.55 AR 350-700nm
The AL1512-A is a high-precision aspheric lens, meticulously crafted by Thorlabs. This lens boasts a 15 mm diameter and is constructed from S-LAH64, a high-quality optical glass by Ohara. The lens is designed for a wavelength of 780 nm and features an effective focal length (EFL) of 12 mm, making it suitable for a wide range of applications.
The aspheric design of the lens, combined with its high numerical aperture (NA) of 0.55, ensures superior image quality and light gathering capability. The lens is CNC polished, guaranteeing exceptional surface accuracy and finish.
The lens is coated with a broadband anti-reflection (AR) coating, optimized for the 350-700 nm range. This coating reduces surface reflections, enhancing transmission and improving overall system performance.
The lens has a center thickness of 5.3 mm and an edge thickness of 2.1 mm, providing robustness and durability. The lens's geometry also includes a front radius of curvature (R1) of 9.32 mm and a conic constant (K1) of -1, further enhancing its optical performance.
