AC050-008-C 5 mm Dia. N-LAK22/N-SF6 Unmounted Achromatic Doublet; EFL=7.5mm 1050-1700nm

The AC050-008-C is a high-quality unmounted achromatic doublet lens, sourced from the renowned optical component manufacturer, Thorlabs. This lens is specifically designed for use within the 1050-1700nm wavelength range, making it an ideal choice for a wide range of applications within the infrared spectrum.

The lens features a base shape of a circle, with a diameter of 5mm. It has a thickness of 3.1mm at the edge, and its geometry includes an inner radius of 0mm, an outer radius of 0mm, r1 of 4.6mm, r2 of -3.9mm, and r3 of -23.9mm. The lens's center thickness is 2.5mm for the first center and 1.5mm for the second.

The AC050-008-C is composed of two materials: N-LAK22 from Schott and N-SF6 from Schott. These materials have been carefully selected for their optical properties, ensuring the lens delivers optimal performance within its specified wavelength range.

The lens is coated with Thorlabs' proprietary AC1050-1700-C coating on both the front and back surfaces. This coating is designed to enhance the lens's performance within the 1050-1700nm wavelength range, providing improved transmission and reduced reflection.

In terms of shape, the AC050-008-C is a multiplet lens. This means it is composed of multiple optical elements, each with its own specific curvature and refractive index, designed to work together to focus light accurately.

The lens is currently in stock and available for immediate purchase from Thorlabs' website. With its high-quality materials, advanced coating, and precise geometry, the AC050-008-C is an excellent choice for any application requiring a high-performance lens within the 1050-1700nm wavelength range.
