AC254-045-B-ML 25.4 mm Dia. N-LAK22/N-SF6HT Mounted Achromatic Doublet; EFL=45mm 650-1050nm

The AC254-045-B-ML is a mounted achromatic doublet lens, designed and manufactured by Thorlabs. This lens is specifically engineered for use within the spectral range of 650-1050nm, making it suitable for a wide range of applications within this wavelength.

The lens features a 25.4mm diameter, providing a substantial surface area for light transmission. The lens is constructed from two types of Schott glass, N-LAK22 and N-SF6HT, each chosen for their specific optical properties. These materials contribute to the lens's overall performance, particularly in terms of chromatic aberration correction and transmission efficiency.

The lens's geometry is intricately designed, with various radii (r1=29.38mm, r2=-25.05mm, r3=-127.06mm) and thicknesses (edge thickness=5.9mm, center thickness 1=7.8mm, center thickness 2=1.6mm) to optimize its optical performance. The lens is coated with Thorlabs' AC650-1050-B coating on both the front and back surfaces, further enhancing its performance within the specified wavelength range.
