SLB-08B-12P 8.0 mm Dia. x 12.5 mm FL; Double-Convex Lens Uncoated

The SLB-08B-12P is a high-quality double-convex lens, sourced from the reputable optical component manufacturer, OptoSigma. This lens is designed with a base shape of a circle and features a spherical geometry, making it suitable for a wide range of optical applications.

The lens has a diameter of 8.0 mm, ensuring a compact design while maintaining excellent optical performance. The edge thickness is 1.5 mm, and the center thickness is 2.8 mm, providing a robust structure that can withstand typical handling and usage. The effective focal length (EFL) of this lens is 12.5 mm, making it ideal for applications that require a longer focal length.

The curvature of the lens is defined by its first and second radii of curvature, R1 and R2, which are 12.46 mm and -12.46 mm respectively. These values indicate a symmetric, double-convex lens, which is beneficial for applications that require minimal spherical aberration. The back focal length (BFL) of this lens is 11.5 mm, which is an important consideration for optical system design.

The lens is made from N-BK7 Schott glass, a popular material for optical components due to its excellent optical properties and chemical durability. The lens is uncoated, which means it does not have any anti-reflective or other coatings. This may be suitable for applications where such coatings are not required or desirable.

The lens is designed to operate at a wavelength of 546.1 nm, which is in the middle of the visible light spectrum. This makes it suitable for a wide range of applications, including imaging, illumination, and beam shaping.
