AL1225-B 12.5 mm Dia. S-LAH64 High-Precision; CNC Polished Aspheric Lenses; EFL=25 mm; NA=0.23 AR 650-1050nm
The AL1225-B is a high-precision aspheric lens, meticulously crafted by Thorlabs. This lens boasts a 12.5 mm diameter and a focal length of 25 mm, making it an ideal choice for a wide range of optical applications.
The lens is constructed from n-BK7 Schott, a high-quality optical glass, and features a CNC-polished surface for superior optical performance. The aspheric design of the lens helps to minimize spherical aberration, enhancing the overall image quality.
The lens is coated with a broadband anti-reflective coating, optimized for the 650-1050 nm range. This coating significantly reduces surface reflections, thereby improving light transmission and enhancing the overall system performance.
The lens has a numerical aperture (NA) of 0.23, which determines the light-gathering ability of the lens. A higher NA allows for a wider angle of acceptance and a sharper image.
The lens is 2.5 mm thick at the edge and 4 mm thick at the center. It has a clear aperture, with no inner or outer radius specified, making it suitable for a wide range of applications.
