ACL25416U-A ø1" Aspheric Condenser Lens; f=16 mm, NA=0.79 AR 350-700nm

The ACL25416U-A is a high-quality aspheric condenser lens, boasting a focal length of 16 mm and a numerical aperture (NA) of 0.79. This lens is designed for use in the visible spectrum, specifically optimized for wavelengths of 633 nm. Manufactured by Thorlabs, a trusted name in the optical industry, this lens is constructed from B270 Schott glass, a popular choice for its excellent optical properties and durability.

The lens features a circular base shape with a diameter of 25.4 mm, making it compatible with a wide range of optical systems. The edge thickness is 1.2 mm, while the center thickness is 14 mm, providing robustness and stability. The lens's geometry includes a front surface radius of 8.818197 mm and a back surface radius of -69.99948 mm. The effective focal length (EFL) is 7.3 mm, and the lens has a conic constant of -0.9991715.

The ACL25416U-A is coated with a broadband anti-reflective coating, specifically designed for wavelengths ranging from 350 nm to 700 nm. This coating reduces surface reflections, enhancing the overall transmission of the lens. The lens's shape is aspheric, which helps to minimize spherical aberration, thereby improving the image quality.
