SBC022AR.16 25.4 mm Dia. x -200 mm FL; NIR coated; Double-Concave Lens 650-1000nm
The SBC022AR.16 is a high-quality double-concave lens, designed with a base shape of a circle and a diameter of 25.4 mm. This lens is sourced from the reputable vendor MKS/Newport, and it is currently in stock, as indicated by its weblink status. The lens features a significant focal length of -200 mm, making it suitable for a wide range of optical applications.
The lens is made from UVFS Mal-1965, a material known for its optical transparency and durability. It has a center thickness of 2.5 mm and an edge thickness of 3.21 mm, providing a robust structure that can withstand handling and use in various environments. The lens's effective focal length (EFL) is -200 mm, and its back focal length (BFL) is -200.85 mm, which are crucial specifications for precise optical system design.
The SBC022AR.16 is coated with New AR-16 fromfigure on both the front and back surfaces. This anti-reflective coating is specifically designed for the near-infrared (NIR) region, covering the wavelength range of 650-1000 nm. This coating enhances the lens's performance by reducing surface reflections, thereby increasing transmission and improving image quality.
