SLB-50-90PIR2 50.0 mm Dia. x 90.0 mm FL; Coated; Plano-Convex Lens 750-1550nm
The SLB-50-90PIR2 is a Plano-Convex Spherical Lens, sourced from OptoSigma, with a diameter of 50.0 mm and a focal length of 90.0 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 fabricated 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 center thickness of 10.3 mm and an edge thickness of 3 mm. This geometry, combined with the lens's diameter and focal length, results in an EFL (Effective Focal Length) of 90.0 mm and a Back Focal Length (BFL) of 83.2 mm.
The SLB-50-90PIR2 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.
