AL108-B 10 mm Dia. S-LAH64 High-Precision; CNC Polished Aspheric Lenses; EFL=8 mm; NA=0.55 AR 650-1050nm
The AL108-B is a high-precision aspheric lens, meticulously crafted by Thorlabs. This lens boasts a 10 mm diameter and is constructed from S-LAH64, a high-quality material from Ohara. The lens is designed for use with a wavelength of 780 nm and features an effective focal length (EFL) of 8 mm, making it suitable for a wide range of optical applications.
The aspheric design of the AL108-B, combined with its CNC polished surface, ensures superior optical performance. The lens's geometry includes an inner radius of 0, an outer radius of 0, a thickness at the edge of 1.6 mm, and a thickness at the center of 3.7 mm. The lens's high numerical aperture (NA) of 0.55 further enhances its light-gathering capabilities.
The AL108-B is coated with THo BBAR, a broadband anti-reflection coating that covers the wavelength range of 650-1050 nm. This coating reduces surface reflections, thereby improving transmission and overall system performance. The lens's shape is aspheric, which helps to minimize spherical aberration and other optical distortions, thereby delivering sharp, clear images.
