32-921 40 mm Dia. N-SSK8/N-SF10 Achromatic Doublet; EFL=120mm MgF2 400-700nm
The 32-921 is a high-quality achromatic doublet lens, sourced from the renowned optical vendor, Edmund Optics. This lens is specifically designed for use in the 400-700nm spectral range, making it suitable for a wide range of applications in the visible light spectrum.
The lens features a 40mm diameter and an effective focal length (EFL) of 120mm, providing a substantial working distance and a wide field of view. The achromatic design, which combines two different types of glass (N-SSK8 and N-SF10), effectively corrects chromatic aberration, ensuring sharp, clear images free from color fringing.
The lens surfaces are coated with MgF2, a standard coating that provides high transmission across the visible spectrum. This coating also offers excellent environmental stability, making the lens suitable for use in various conditions.
The lens geometry includes a central thickness of 9.6mm and edge thickness of 10.51mm, providing robustness and rigidity. The lens also features a multiplet shape, which is a complex structure composed of multiple elements. This design allows for precise control over optical properties, making the lens ideal for high-performance applications.
