SPC019AR.16 25.4 mm Dia. x -250 mm FL; NIR coated; Plano-Concave Lens 650-1000nm
The SPC019AR.16 is a Plano-Concave Spherical Lens, sourced from the reputable vendor MKS/Newport. This lens boasts a diameter of 25.4 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 is made from UVFS Mal-1965, a material known for its excellent optical properties. The geometry of the lens is meticulously designed, with a thickness at the edge of 3.07 mm and a center thickness of 2.5 mm. The inner and outer radii are 0 mm, indicating a uniform curvature. The back focal length is -251.71 mm, which is slightly longer than the focal length, suggesting a slight divergence of the emerging beam.
The lens is coated with New AR-16 fromfigure on both the front and back surfaces. This anti-reflection coating is specifically designed for the near-infrared (NIR) region, covering the wavelength range of 650-1000 nm. This coating reduces surface reflections, enhancing the transmission of light through the lens and improving the overall system performance.
