SLB-40-200PIR2 40.0 mm Dia. x 200.0 mm FL; Coated; Plano-Convex Lens 750-1550nm
The SLB-40-200PIR2 is a Plano-Convex Spherical Lens, sourced from OptoSigma, with a diameter of 40.0 mm and a focal length of 200.0 mm. This lens is made from n-bk7 schott material, a popular choice for its excellent optical properties and versatility. The lens has a front and back coating of opt ir2, which enhances its performance in the 750-1550nm wavelength range.
The lens geometry includes a thickness edge of 2.0 mm and a thickness center of 3.9 mm. The inner and outer radii are 0 mm, and the effective focal length (EFL) is 200.0 mm. The lens's front surface has a radius of curvature (R1) of 103.8 mm, and the back focal length (BFL) is 197.4 mm.
This lens is designed for use in applications that require a broad wavelength range and high-quality optical performance. Its Plano-Convex design allows for efficient light collection and minimal spherical aberration. The opt ir2 coating ensures high transmission and low reflectance, making it ideal for use in systems where light loss must be minimized.
