ACL1210U-B 12 mm Aspheric Condenser Lens; f=10.5 mm, NA=0.54 AR 650-1050nm

The ACL1210U-B is a high-quality aspheric condenser lens, designed and manufactured by Thorlabs. This lens is specifically engineered for use in a wide range of optical applications, thanks to its superior optical performance and versatile specifications.

The lens features a focal length of 10.5 mm, indicated by the 'f=10.5 mm' in its name. This focal length, combined with its 12 mm diameter, makes it a compact and efficient choice for various setups. The lens's numerical aperture (NA) is 0.54, which is quite high for a condenser lens, suggesting its ability to collect and focus light efficiently.

The ACL1210U-B is made from B270 Schott glass, a common and reliable material in the optical industry. This material ensures excellent optical transmission and durability. The lens's aspheric design further enhances its performance, reducing spherical aberration and providing a clearer, sharper image.

The lens is coated with a broadband anti-reflective coating, suitable for wavelengths between 650 and 1050 nm. This coating reduces unwanted reflections and increases the lens's overall transmission, making it more efficient in transmitting light.

In terms of physical dimensions, the lens has a thickness of 1.9 mm at the edge and 5.8 mm at the center. The inner and outer radii are 0, indicating a circular shape. The back focal length is 7 mm.
