SLB-15B-90PIR2 15.0 mm Dia. x 90.4 mm FL; Coated; Double-Convex Lens 750-1550nm
The SLB-15B-90PIR2 is a spherical lens with a base shape of a circle, designed and manufactured by OptoSigma. This lens is part of their n-bk7 biconvex lenses series, which is optimized for use in the infrared spectrum, specifically between 750-1550nm.
The lens has a diameter of 15.0 mm and a thickness at the edge of 2.0 mm, while the center thickness is 2.6 mm. The effective focal length (EFL) of this lens is 90.4 mm, making it suitable for applications that require a longer focal length. The first radius of curvature (R1) is 93.42 mm, and the second radius of curvature (R2) is -93.42 mm, indicating a double-convex lens design. The back focal length (BFL) is 89.6 mm.
The lens is made of n-bk7 Schott glass, a popular material for optical lenses due to its excellent optical properties and wide transparency range. The lens is coated with Opt IR2 on both the front and back surfaces, a coating specifically designed for the infrared spectrum, enhancing its performance in this range.
