ACL4532U-B ø45 mm Aspheric Condenser Lens; f=32.1 mm, NA=0.60 AR 650-1050nm

The ACL4532U-B is a high-quality aspheric condenser lens, designed and manufactured by Thorlabs. This lens boasts a catalog number of ACL4532U-B and is available for purchase directly from the vendor's website. The lens is currently in stock, ensuring quick delivery for your optical system needs.

The lens is specifically designed for use in the visible spectrum, with a central wavelength of 633nm. It is constructed from B270 Schott glass, a popular material known for its excellent optical properties and durability. The lens features a circular base shape, with a diameter of 45mm and a thickness of 2.2mm at the edge.

The ACL4532U-B has an effective focal length of 32.1mm, making it suitable for a wide range of applications. The lens's front surface is defined by a conic constant of -1, while the back surface is planar. The lens's front and back surfaces are coated with a broadband anti-reflective coating, optimized for the 650-1050nm range, which reduces surface reflections and improves overall transmission.

The lens's aspheric design allows for superior optical performance compared to traditional spherical lenses. The front surface of the lens is defined by a fourth-order polynomial, with a peak-to-valley surface error of λ/4 at 633nm. This results in a high numerical aperture of 0.6, enabling the lens to collect and focus light efficiently.
