SLB-40-250PIR1 40.0 mm Dia. x 250.0 mm FL; Coated; Plano-Convex Lens 633-1064nm
The SLB-40-250PIR1 is a Plano-Convex Spherical Lens, sourced from OptoSigma, with a diameter of 40.0 mm and a focal length of 250.0 mm. This lens is made from n-bk7 schott material, a popular choice for its high refractive index and low dispersion. The lens's geometry includes a 2mm thickness at the edge and a 3.6mm thickness at the center, with an effective focal length (EFL) of 250.7mm and a back focal length (BFL) of 247.7mm.
The lens features a coating of opt ir1 on both the front and back surfaces, designed to enhance its performance within the wavelength range of 633-1064nm. This coating reduces reflection and increases transmission, making the lens ideal for use in various applications such as imaging, beam shaping, and laser systems.
The lens's base shape is circular, and its geometry is spherical, making it suitable for a wide range of optical systems. The item data also indicates that the lens's inner and outer radii are both 0, suggesting a symmetrical design.
