SLB-50-450PIR1 50.0 mm Dia. x 450.0 mm FL; Coated; Plano-Convex Lens 633-1064nm

The SLB-50-450PIR1 is a Plano-Convex Spherical Lens, sourced from OptoSigma, with a diameter of 50.0 mm and a focal length of 450.0 mm. This lens is made of n-bk7 schott material, a popular choice for its high refractive index and low dispersion, making it ideal for a wide range of applications.

The lens's geometry includes a thickness edge of 3.0 mm and a thickness center of 4.3 mm. The inner and outer radii are both zero, indicating a circular shape. The lens's effective focal length (EFL) is 450.0 mm, and the back focal length (BFL) is 447.1 mm. The front and back of the lens are coated with opt ir1, a coating that enhances the lens's performance in the infrared spectrum, specifically between 633-1064nm.

This lens is part of OptoSigma's extensive catalog of optical elements, and the provided weblink indicates that it is currently in stock. The detailed specifications and high-quality materials make this lens a reliable choice for various applications, particularly those requiring infrared transmission.
