23-022 50mm Dia. N-SF6 Precision Aspheric Lens; EFL=50mm; NA=0.5 NIR-Plus 600-1050nm
The 23-022 is a high-precision aspheric lens, designed and manufactured by Edmund Optics. This lens is characterized by its 50mm diameter and a numerical aperture (NA) of 0.5, specifically designed for use in the near-infrared (NIR) spectrum, between 600 and 1050nm.
The lens is made from N-SF6 Schott glass, a material known for its excellent optical properties and durability. The aspheric design of the lens helps to reduce spherical aberration, a common issue in traditional lenses, resulting in improved image quality and resolution.
The lens has an effective focal length (EFL) of 50mm, making it suitable for a wide range of applications. The inner and outer radii of the lens are 0, indicating a flat surface on both sides. The lens has a thickness of 5.08mm at the edge and 13.06mm at the center.
The lens is coated with Edmund Optics' NIR-Plus 600-1050nm coating on both the front and back surfaces. This coating is designed to enhance the lens' performance in the NIR spectrum, reducing reflection and increasing transmission.
The lens is currently in stock and available for purchase through the Edmund Optics website. The provided weblink provides direct access to the product page for easy ordering and further information.
