SBC028AR.16 25.4 mm Dia. x -100 mm FL; NIR coated; Double-Concave Lens 650-1000nm
The SBC028AR.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. The lens features a significant focal length of -100 mm, making it suitable for a wide range of applications.
The lens is made from UVFS MAL-1965 material, which is known for its excellent optical properties. It has a center thickness of 2.5 mm and an edge thickness of 3.92 mm, providing a robust and durable structure. The lens's effective focal length (EFL) is -100 mm, and its back focal length (BFL) is -100.85 mm.
The SBC028AR.16 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 surface reflections, improving the lens's transmission and overall optical efficiency.
The lens's geometry includes a first radius (R1) of -92.192 mm and a second radius (R2) of 92.192 mm. The inner and outer radii are both 0 mm, indicating a uniform curvature. This double-concave lens shape is ideal for applications requiring a negative focal length.
