ACL1815U-B 18 mm Aspheric Condenser Lens; f=15 mm, NA=0.57 AR 650-1050nm
The ACL1815U-B is an 18 mm Aspheric Condenser Lens offered by Thorlabs, designed with a focal length of 15 mm and a numerical aperture of 0.57. This lens is made of B270 Schott glass, ensuring high optical quality and precision. The lens features an antireflection coating optimized for the 650-1050 nm wavelength range, minimizing surface reflections and increasing overall transmission.
The ACL1815U-B has a front radius of curvature (R1) of 7.818 mm and a back focal length (BFL) of 10 mm. The lens's edge thickness is 2 mm, while its center thickness is 8.2 mm. The aspheric design helps reduce spherical aberration and field curvature, providing improved image quality over a larger field of view compared to traditional spherical lenses.
This condenser lens is suitable for various applications, including microscopy, beam shaping, and illumination systems. Its robust construction and high-quality materials ensure longevity and reliable performance, making it an excellent choice for demanding optical systems.
