SBC031AR.33 25.4 mm Dia. x -75 mm FL; Double-Concave Lens Laser V-Coat 1064nm
The SBC031AR.33 is a high-quality spherical lens, specifically designed for use in laser applications, with a wavelength of 1064nm. This lens is sourced from the reputable vendor MKS/Newport, ensuring reliable performance and durability.
The lens boasts a base shape of a circle, with a diameter of 25.4 mm, making it suitable for a wide range of applications. The thickness at the edge is 4.4 mm, while the center thickness is 2.5 mm, providing a robust structure. The effective focal length (EFL) of this lens is -75 mm, indicating its double-concave nature, which is ideal for focusing or diverging light beams.
The SBC031AR.33 features a unique geometry, with inner and outer radii of 0, and radii of curvature (R1 and R2) of -69.241 mm and 69.241 mm respectively. This geometry contributes to its excellent optical performance. The back focal length (BFL) is -75.85 mm, which should be considered when integrating this lens into an optical system.
The lens is made from UVFS Mal-1965 material, a common choice for its excellent optical properties. It comes with a front and back coating of New AR-33, which enhances its performance in laser applications by reducing reflection and increasing transmission.
