SLB-30B-40PIR2 30.0 mm Dia. x 41.3 mm FL; Coated; Double-Convex Lens 750-1550nm
The SLB-30B-40PIR2 is a high-quality lens from OptoSigma, designed for use in the 750-1550nm wavelength range. This lens is a Spherical Lens (Convex-Convex) type, featuring a Base Shape of Circular and a Sub Type of Spherical Lens (Convex-Convex).
The lens has a diameter of 30.0 mm and a thickness edge of 2.0 mm. The thickness center is 7.6 mm, and the Effective Focal Length (EFL) is 41.3 mm. The first radius of curvature (R1) is 41.52 mm, and the second radius of curvature (R2) is -41.52 mm, indicating a double-convex lens. The Back Focal Length (BFL) is 38.7 mm, and both the Inner and Outer Radius are 0 mm.
The lens is made of n-bk7 schott material, a popular choice for its high refractive index and low dispersion. The lens is coated with opt ir2 on both the front and back, providing excellent anti-reflective properties in the specified wavelength range.
