SPC043AR.16 50.8 mm Dia. x -250 mm FL; NIR coated; Plano-Concave Lens 650-1000nm
The SPC043AR.16 is a Plano-Concave Spherical Lens, sourced from the reputable vendor MKS/Newport. This lens boasts a diameter of 50.8 mm and a focal length of -250 mm, making it ideal for applications that require a negative focal length. The lens is constructed with a base shape of Circular, ensuring a wide field of view.
The lens's geometry is meticulously designed, with a thickness edge of 4.8 mm and a thickness center of 2.5 mm. The back focal length (bfl) is -251.71 mm, and the inner and outer radii are 0 mm, indicating a plano surface on both sides. The effective focal length (efl) is -250 mm, which is the distance from the lens's principal point to the focal point.
The lens is made from UVFS Mal-1965 material, a unique type of glass known for its excellent optical properties. The lens is coated with New AR-16 on both the front and back surfaces, enhancing its performance in the near-infrared (NIR) spectrum, specifically between 650 and 1000 nm. This coating reduces reflective losses, thereby increasing the amount of light transmitted through the lens.
