AC508-150-C 50.8 mm Dia. N-LAK22/N-SF6 Unmounted Achromatic Doublet; EFL=150.2mm 1050-1700nm

The AC508-150-C is a high-quality achromatic doublet lens, sourced from the renowned optical component manufacturer, Thorlabs. This lens, with a diameter of 50.8 mm, is designed for use in the infrared spectrum, specifically between 1050nm and 1700nm, making it ideal for a wide range of applications in this spectral range.

The lens is a multiplet, meaning it is composed of multiple elements, in this case, two, made from different materials: N-LAK22 and N-SF6, both from Schott. This combination of materials helps to correct chromatic aberrations, ensuring high-quality imaging or light focusing. The lens has a focal length of 150.2mm, providing a moderate magnification and field of view.

The lens is unmounted, meaning it does not come with any housing or mounting hardware. This allows for flexibility in integration, as it can be mounted in a variety of ways to suit the specific application. However, it does require a certain level of expertise in optical system design and assembly.

The lens is coated with Thorlabs' AC1050-1700-C coating on both the front and back surfaces. This anti-reflection coating is designed to reduce surface reflections and increase transmission in the 1050-1700nm range, further enhancing the lens' performance in infrared applications.
