SLB-80-300PIR2 80.0 mm Dia. x 300.0 mm FL; Coated; Plano-Convex Lens 750-1550nm

The SLB-80-300PIR2 is a Plano-Convex Spherical Lens, sourced from OptoSigma, with a diameter of 80.0 mm and a focal length of 300.0 mm. This lens is designed for use within the wavelength range of 750-1550nm, making it suitable for a variety of applications within this spectrum.

The lens is constructed from n-bk7 schott, a popular material in optical applications due to its excellent optical properties. The lens features a Plano-Convex geometry, with a thickness at the edge of 3.0 mm and a thickness at the center of 8.2 mm. The lens's effective focal length (EFL) is 300.0 mm, and its back focal length (BFL) is 294.6 mm. The radius of curvature for the first surface (R1) is 155.7 mm.

The SLB-80-300PIR2 is coated with Opt IR2 on both the front and back surfaces. This coating enhances the lens's performance within its specified wavelength range, providing improved transmission and reduced reflection. The lens's circular shape allows for versatile application, and its dimensions make it suitable for use in systems requiring larger optical elements.
