SLB-08-15P 8.0 mm Dia. x 15.0 mm FL; Plano-Convex Lens Uncoated

The SLB-08-15P is a Plano-Convex Lens, sourced from the reputable optical components manufacturer, OptoSigma. This lens, with a base shape of a circle, is designed for use in a wide range of optical applications.

The lens has a diameter of 8.0 mm, making it suitable for use in compact optical systems. The thickness of the lens at the edge is 1.5 mm, while the center thickness is 2.6 mm. This variation in thickness is due to the Plano-Convex geometry of the lens, where one side is flat (plano) and the other side is curved (convex).

The Effective Focal Length (EFL) of this lens is 15.0 mm. This is the distance from the lens's principal point on the convex side to the focal point, and it determines the lens's magnification power. The radius of curvature (R1) of the convex side is 7.79 mm.

The Back Focal Length (BFL) of this lens is 13.3 mm. This is the distance from the lens's rear principal plane to the focal point. The Inner Radius and Outer Radius of the lens are both 0 mm, indicating that the lens is uniformly curved.

The lens is made of n-BK7 Schott, a popular optical glass due to its excellent optical properties and high Abbe number. The wavelength for this lens is 546.1 nm.

Notably, this lens is uncoated. Coatings are often applied to lenses to reduce reflection, increase transmission, or to modify the lens's dispersive properties. However, this lens, in its uncoated form, offers a different set of advantages, such as lower cost and simplicity.
