SLB-20-50PIR2 20.0 mm Dia. x 50.0 mm FL; Coated; Plano-Convex Lens 750-1550nm
The SLB-20-50PIR2 is a Plano-Convex Spherical Lens, sourced from OptoSigma, designed for use within the wavelength range of 750-1550nm. This lens boasts a circular base shape, with a diameter of 20.0 mm and a thickness of 2.0 mm at the edge, transitioning to 4.0 mm at the center. The Effective Focal Length (EFL) of this lens is 50.0 mm, and the Radius of Curvature (R1) is 25.95 mm.
The Back Focal Length (BFL) of this lens is 47.4 mm, and it does not have an Inner Radius or Outer Radius, as it is a Plano-Convex lens. The Material ID for this lens is n-bk7 schott, a popular choice for its high refractive index and low dispersion.
The lens features a coating on both the front and back surfaces, specifically an opt IR2 coating, which is designed to enhance performance within the specified infrared wavelength range. This lens is currently in stock and available for immediate purchase, as indicated by its valid weblink status.
