SLB-80B-150P 80.0 mm Dia. x 152.2 mm FL; Double-Convex Lens Uncoated

The SLB-80B-150P is a high-quality double-convex lens, sourced from the reputable 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 80.0 mm, providing a substantial surface area for light transmission. The edge thickness is 3.0 mm, while the center thickness is 13.5 mm, indicating a robust construction that can withstand typical handling and usage. The effective focal length (EFL) of this lens is 152.2 mm, making it suitable for applications that require moderate magnification or light bending.

The curvature of the lens is defined by its first and second radii of curvature, R1 and R2, which are 155.7 mm and -155.7 mm respectively. These values suggest a symmetrical design, which can help to minimize optical aberrations. The back focal length (BFL) of the lens is 147.8 mm, a critical factor to consider when designing an optical system to ensure adequate clearance and alignment.

The lens is made from n-BK7 Schott, a popular optical glass due to its excellent optical properties and versatility. This material has a refractive index of 1.5168 at the specified wavelength of 546.1 nm. The lens is uncoated, which may be desirable in certain applications where a specific coating is not required or where cost is a consideration.
