ACL108U-A ø10 mm Aspheric Condenser Lens; f=8 mm, NA=0.61 AR 350-700nm

The ACL108U-A is a high-quality aspheric condenser lens, designed and manufactured by Thorlabs. This lens boasts a catalog number of ACL108U-A 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 light spectrum, with a central wavelength of 633nm. It is constructed from B270 Schott glass, a popular material for its high transmittance and excellent optical properties. The lens features a circular base shape, with a diameter of 10mm, making it suitable for a wide range of applications.

The ACL108U-A has a focal length of 8mm, indicated by the 'f=8 mm' in its name. This focal length, combined with its numerical aperture (NA) of 0.61, allows the lens to focus light efficiently onto a small spot, making it ideal for use in high-resolution imaging systems or as a condenser lens in microscopy.

The lens's geometry includes an inner radius of 0mm, an outer radius of 0mm, and a thickness at the edge of 2.1mm. The effective focal length (EFL) is 8mm, and the back focal length (BFL) is 4mm. The lens's center thickness is 5.8mm, providing structural rigidity and minimizing optical distortions.

The ACL108U-A features an advanced aspheric design, with coefficients k1=-0.6027, a4front=0.000221, and all other higher-order coefficients equal to zero. This design reduces spherical aberration and other optical aberrations, enhancing the lens's performance in imaging applications.

The lens is coated with a broadband anti-reflection coating (AR) that covers the wavelength range of 350-700nm. This coating reduces surface reflections, improving light transmission through the lens and reducing unwanted glare and ghosting.
