SLB-40B-100P 40.0 mm Dia. x 101.0 mm FL; Double-Convex Lens Uncoated
The SLB-40B-100P is a high-quality double-convex lens, sourced from the reputable optical vendor, OptoSigma. This lens, with a base shape of a circle, is designed for use in a wide range of optical applications, thanks to its precise geometry and material composition.
The lens has a diameter of 40.0 mm and a center thickness of 5.9 mm, ensuring a substantial optical path while maintaining a compact form factor. The edge thickness is 2.0 mm, providing robustness and durability. The effective focal length (EFL) of this lens is 101.0 mm, making it suitable for applications that require moderate magnification and a large field of view.
The SLB-40B-100P is made from n-BK7 Schott, a popular optical glass due to its excellent optical properties and versatility. This lens is uncoated, offering users the flexibility to apply their preferred coating based on their specific application requirements.
The lens's surface radii are R1 = 103.8 mm and R2 = -103.8 mm, which are symmetric and indicate a strongly converging lens. The back focal length (BFL) is 99.0 mm, which should be considered when designing the optical system to ensure sufficient clearance for the detector or subsequent optical elements.
