ACL12708U-A ⅜” Aspheric Condenser Lens; f=8 mm, NA=0.78 AR 350-700nm

The ACL12708U-A is a high-quality ⅜” (12.7 mm) Aspheric Condenser Lens, designed with an effective focal length (EFL) of 8 mm and a numerical aperture (NA) of 0.78. This lens is sourced from the renowned optical component manufacturer, Thorlabs, and is specifically designed for use in applications that require a high-performance condenser lens with excellent light gathering capabilities.

The lens is made from B270 Schott glass, a popular choice for its high transmission and low auto-fluorescence properties. The lens features an aspheric design, which provides superior image quality by reducing spherical aberration, coma, and other optical aberrations often associated with traditional spherical lenses. The lens has a clear aperture of 12.7 mm and a thickness of 1.6 mm at the edge, ensuring excellent optical performance even in applications that require high light throughput.

The ACL12708U-A is coated with Thorlabs' anti-reflection coating, which is designed to reduce surface reflections and increase transmission in the 350-700 nm spectral range. This coating ensures high transmission and low reflectance, making it ideal for use in applications such as microscopy, beam shaping, and laser applications.

The lens has a front and back coating of tho a bbar, which provides excellent protection against environmental factors such as dust, moisture, and scratches. The lens also features a center thickness of 7.5 mm, providing excellent mechanical stability and resistance to deformation.
