AC254-060-A 25.4 mm Dia. E-BAF11/FD10 Unmounted Achromatic Doublet; EFL=60.1mm 400-700nm

The AC254-060-A is a high-quality achromatic doublet lens, unmounted, with a diameter of 25.4 mm, and a focal length of 60.1mm. This lens is designed for use in the 400-700nm spectral range, making it suitable for a wide range of applications in the visible spectrum.

The lens is composed of two elements, E-BAF11 from Thorlabs and E-FD10 from Hoya, which are renowned for their optical quality. The first element has a radius of curvature of 41.7mm, while the second element has a radius of curvature of -25.9mm and -230.7mm. The lens has a thickness of 8.2mm at the edge and 8mm and 2.5mm at the center.

The lens is coated with THo AC400-700-A, a broadband anti-reflection coating designed for use in the 400-700nm range. This coating reduces surface reflections, increasing the amount of light transmitted through the lens.

The lens is a multiplet, meaning it is composed of multiple elements. This design provides superior optical performance, reducing chromatic aberration and improving image quality. The lens is unmounted, providing users with the flexibility to integrate it into their own optical systems.

The lens is available from Thorlabs, a leading manufacturer of optical components. According to the vendor, the lens is in stock, ensuring quick delivery times. The lens's catalog number is AC254-060-A, and it can be found on Thorlabs' website using this number.
