SLB-08B-15P 8.0 mm Dia. x 15.4 mm FL; Double-Convex Lens Uncoated

The SLB-08B-15P is a high-quality double-convex lens, sourced from the reputable optical component manufacturer, 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 8.0 mm, ensuring a substantial light-gathering capacity. It features a thickness of 1.5 mm at the edge, which gradually increases to 2.5 mm at the center, providing structural rigidity and minimizing optical distortions. The effective focal length (EFL) of this lens is 15.4 mm, making it suitable 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 15.57 mm and -15.57 mm respectively. These values indicate a symmetrical, double-convex lens, which is known for its ability to focus light to a single point, making it ideal for imaging and beam focusing applications.

The lens is made from n-BK7 Schott, a high-grade optical glass known for its excellent optical properties, including a high refractive index and low dispersion. This makes the lens suitable for use across a wide range of wavelengths, with a specified wavelength of 546.1 nm.

Notably, this lens is uncoated. While coatings can enhance the performance of lenses by reducing reflections and increasing transmission, an uncoated lens can be advantageous in certain applications where a natural chromatic aberration is desired, or where cost or simplicity are primary considerations.
