SBC019AR.16 25.4 mm Dia. x -250 mm FL; NIR coated; Double-Concave Lens 650-1000nm
The SBC019AR.16 is a high-quality double-concave lens, designed and manufactured by MKS/Newport. This lens, with a base shape of a circle, is specifically engineered for use in the near-infrared (NIR) spectrum, covering the wavelength range of 650-1000nm.
The lens has a diameter of 25.4mm, making it suitable for a wide range of applications. The edge thickness is 3.07mm, while the center thickness is 2.5mm, providing a robust structure and ensuring minimal distortion. The effective focal length (EFL) of this lens is -250mm, indicating its concave nature.
The SBC019AR.16 features a unique coating on both the front and back surfaces. This AR-16 coating, applied using the New fromfigure method, enhances the lens's performance in the NIR spectrum, reducing surface reflections and increasing transmission.
The lens's geometry includes an inner radius of 0mm and an outer radius of 0mm, indicating a simple spherical shape. The back focal length (BFL) is -250.85mm, slightly longer than the EFL due to the lens's concave design.
This lens is made from UVFS Mal-1965, a material specifically chosen for its optical properties in the NIR spectrum. The lens is in stock and available for immediate purchase, as indicated by its valid weblink status.
