ACL7560U ø75 mm Aspheric Condenser Lens; f=60 mm, NA=0.61 Uncoated

The ACL7560U is a high-quality ø75 mm Aspheric Condenser Lens, designed with a focal length of 60 mm and a numerical aperture (NA) of 0.61. This lens is sourced from Thorlabs, a renowned vendor known for their precision optical components.

The lens is crafted from B270 Schott glass, a popular choice for its excellent optical properties and durability. The aspheric design of the lens ensures superior image quality by minimizing spherical aberration, a common issue in traditional spherical lenses. This makes the ACL7560U an ideal choice for applications that require high resolution and contrast.

The lens has an inner radius of 0 and an outer radius of 0, indicating a circular shape. The diameter of the lens is 75 mm, and it has a thickness of 2.3 mm at the edge. The effective focal length (EFL) is 60 mm, and the back focal length (BFL) is 40 mm. The center thickness of the lens is 30 mm, and it has a high NA of 0.61, indicating a wide acceptance angle for light.

The lens's aspheric surface is defined by the conic constant k1, which is -1.911. The aspheric coefficients a2, a4, a6, and a8 are 0, 5e-06, 0, and 0, respectively, indicating a high degree of precision in the lens's manufacture. The lens is uncoated, allowing users to apply their own coatings to suit their specific application requirements.
