AC127-030-C 12.7 mm Dia. N-LAK22/N-SF6 Unmounted Achromatic Doublet; EFL=30mm 1050-1700nm

The AC127-030-C is a high-quality, unmounted achromatic doublet lens, designed and manufactured by Thorlabs. This lens is specifically engineered for use within the 1050-1700nm wavelength range, making it an ideal choice for a wide array of applications within the infrared spectrum.

The lens features a base shape of a circle, with a diameter of 12.7mm, and is constructed from two distinct materials: N-LAK22 and N-SF6, both from Schott. This unique combination of materials ensures high optical performance and durability. The lens has a thickness of 4.8mm at the edge, with the central thickness varying between 4.7mm and 1.5mm. The inner and outer radii are 0mm, and the first and second radii of curvature are 12.4mm and -14mm respectively, while the third radius of curvature is 65.3mm.

The lens is coated with Thorlabs' proprietary AC1050-1700-C coating on both the front and back surfaces, further enhancing its performance within the specified wavelength range. This coating helps to reduce surface reflections and increase transmission, thereby improving the overall efficiency and quality of the optical system in which it is used.

The AC127-030-C is a multiplet lens, meaning it is composed of multiple optical elements. This design allows for the correction of chromatic aberrations, ensuring high-quality imaging and precise focusing. The lens is unmounted, providing users with the flexibility to integrate it into their own optical systems and setups.
