ACL108U-B ø10 mm Aspheric Condenser Lens; f=8 mm, NA=0.61 AR 650-1050nm

The ACL108U-B is a high-quality aspheric condenser lens, designed and manufactured by Thorlabs. This lens boasts a catalog number of ACL108U-B and is available for purchase directly from the Thorlabs website. The lens is currently in stock, ensuring quick delivery for your optical project needs.

The lens is specifically designed for use in the visible light spectrum, with a central wavelength of 633nm. It is constructed from B270 Schott glass, a popular choice for its high transmission and excellent optical properties.

The ACL108U-B features a circular base shape with a diameter of 10mm. The lens has a thickness of 2.1mm at the edge and 5.8mm at the center. The effective focal length (EFL) of the lens is 8mm, making it suitable for a variety of applications where a compact, high-performance lens is required.

The lens's geometry includes a range of parameters that contribute to its excellent optical performance. The inner radius is 0mm, while the outer radius is also 0mm. The lens has a back focal length (BFL) of 4mm. The lens's conic constant (k1) is -0.6027, and it has a series of aspheric coefficients (a2 to a16) that further enhance its optical properties.

The lens is coated with a broadband anti-reflection coating, specifically designed for the wavelength range of 650-1050nm. This coating reduces surface reflections, improving the overall transmission of the lens and reducing unwanted optical artifacts.

The ACL108U-B is a shape, specifically an aspheric lens. This shape allows for superior optical performance compared to traditional spherical lenses, particularly in terms of reducing spherical aberration and improving focus.
