AC508-300-B-ML 50.8 mm Dia. N-LAK22/N-SF6HT Mounted Achromatic Doublet; EFL=300mm 650-1050nm
The AC508-300-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 ideal for a variety of applications within this range.
The lens features a 50.8mm 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 selected for their specific optical properties. The use of these materials ensures high-quality image reproduction and minimal chromatic aberration.
The lens geometry is complex, with three radii of curvature (r1, r2, and r3) and varying thicknesses at the edge, center 1, and center 2. This design allows for precise control over the lens's optical properties, ensuring optimal 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 spectral range.
The lens is mounted, providing a convenient and secure method of integration into optical systems. According to Thorlabs' website, the lens is currently in stock, ensuring quick and reliable delivery.
