ACL1512U-A 15 mm Aspheric Condenser Lens; f=12 mm, NA=0.61 AR 350-700nm

The ACL1512U-A is a high-quality aspheric condenser lens, designed and manufactured by Thorlabs. This lens boasts a catalog number of ACL1512U-A and is currently in stock, as indicated by its weblink status.

The lens is specifically designed for use in the optical spectrum, with a central wavelength of 633 nm. It is constructed from B270 Schott glass, a popular material for optical elements due to its excellent optical properties and durability.

The ACL1512U-A features a circular base shape with a diameter of 15 mm. It has a thickness of 2.4 mm at the edge, reducing to 8 mm at the center. The effective focal length (EFL) of the lens is 12 mm, and its back focal length (BFL) is 7 mm. The lens has a numerical aperture (NA) of 0.61, indicating a wide acceptance angle and high light-gathering capability.

The lens is coated with a broadband anti-reflective coating, suitable for the 350-700 nm range. This coating reduces surface reflections, improving transmission and image quality. The lens shape is aspheric, which helps to correct spherical aberration and improve the focus and clarity of the image.
