ACL1512U ø15 mm Aspheric Condenser Lens; f=12 mm, NA=0.61 Uncoated

The ACL1512U is a high-quality aspheric condenser lens, 15 mm in diameter, manufactured by Thorlabs. This lens is designed for use with a focal length of 12 mm and a numerical aperture (NA) of 0.61, making it suitable for a wide range of applications that require high-resolution imaging and light collection.

The lens is made from b270 Schott glass, a popular choice for its excellent optical properties and durability. The aspheric design of the lens helps to reduce spherical aberration, a common issue in traditional lenses, which can lead to distorted images. This results in improved image quality and increased light transmission.

The lens has a clear aperture of 15 mm, providing a large field of view. The edge thickness is 2.4 mm, and the center thickness is 8 mm, ensuring structural rigidity and minimizing the risk of deformation. The effective focal length (EFL) is 12 mm, and the back focal length (BFL) is 7 mm, which are crucial specifications for designing optical systems.

The lens is uncoated, which means it does not have any anti-reflective coatings. While this may result in a higher reflectance loss, it also means that the lens is more cost-effective and versatile, as it can be used in a wider range of wavelengths without the risk of coating damage.

The ACL1512U is currently in stock and available for purchase through the Thorlabs website. With its high-quality materials, advanced design, and versatile specifications, this lens is an excellent choice for various applications in fields such as biomedical research, machine vision, and optical metrology.
