SLB-25.4-500PIR1 25.4 mm Dia. x 500.0 mm FL; Coated; Plano-Convex Lens 633-1064nm
The SLB-25.4-500PIR1 is a Plano-Convex Spherical Lens, 25.4 mm in diameter and 500.0 mm in focal length, sourced from OptoSigma. This lens is made from n-bk7 schott material, a popular choice for its excellent optical properties and versatility.
The lens features a Plano-Convex geometry, meaning one side is flat (Plano) and the other is curved (Convex). The radius of curvature for the curved side is 259.5 mm, and the back focal length is 498.4 mm. The lens has a central thickness of 2.3 mm and an edge thickness of 2 mm, providing a robust structure suitable for various applications.
The lens is coated with opt ir1 on both the front and back surfaces, enhancing its performance in the wavelength range of 633-1064nm. This coating reduces reflection and increases transmission, making it ideal for use in laser applications.
