AC254-035-B 25.4 mm Dia. N-BAF10/N-SF6HT Unmounted Achromatic Doublet; EFL=35mm 650-1050nm

The AC254-035-B is a high-quality, unmounted achromatic doublet lens from Thorlabs, designed for use in the 650-1050nm spectral range. This lens is part of Thorlabs' extensive catalog of optical elements, sourced from vendors worldwide, and is available for use in advanced optical simulations in our software.

The lens features a base shape of a circle, with a diameter of 25.4mm. The edge thickness is 7.5mm, while the inner and outer radii are 0mm. The first radius of curvature (r1) is 23.99mm, the second radius (r2) is -18.62mm, and the third radius (r3) is -97.27mm. The center thickness of the first lens is 10.5mm, and the second lens is 1.5mm.

The lens is made from two types of Schott glass: N-BAF10 and N-SF6HT. The front and back surfaces of the lens are coated with Thorlabs' AC650-1050-B coating, designed for use in the 650-1050nm spectral range.

The lens is a multiplet, meaning it is composed of multiple elements. This design allows for superior optical performance, particularly in terms of chromatic aberration correction. The effective focal length (EFL) of the lens is 35mm.

The lens is unmounted, meaning it does not come with a mount for easy integration into optical systems. However, it can be easily mounted using Thorlabs' wide range of mounting options, available separately.

The lens is currently in stock and available for immediate use. For more information, including detailed specifications and purchasing options, please visit the product webpage linked in the item data.
