AL1210 12.5 mm Dia. S-LAH64 High-Precision; CNC Polished Aspheric Lenses; EFL=10 mm; NA=0.55 Uncoated
The AL1210 is a high-precision aspheric lens offered by Thorlabs, designed with a 12.5 mm diameter and a central thickness of 4.3 mm. This lens is crafted from S-LAH64, a high-quality optical glass from Ohara, and features a high numerical aperture (NA) of 0.55. The lens's design includes an effective focal length (EFL) of 10 mm, making it suitable for various applications that require tight focusing or imaging.
The aspheric geometry of the AL1210 is defined by its inner and outer radii, both of which are 0 mm, and its clear aperture. The lens's edges have a thickness of 1.6 mm. The aspheric coefficients, such as k1, k2, a2, a4, a6, a8, a10, and a12, are also provided, allowing for a more detailed understanding of the lens's shape and optical properties.
This lens is uncoated, which means it does not have any anti-reflective coatings. While this may result in higher reflective losses, it also means the lens is more cost-effective and can be used in applications where such coatings are not necessary. The lens's web link is valid and indicates that it is in stock, ensuring quick delivery for your optical projects.
