The SLB-40-900PIR1 is a Plano-Convex Spherical Lens, sourced from OptoSigma, with a diameter of 40.0 mm and a focal length of 900.0 mm. This lens is made from n-bk7 schott material, a popular choice for its high refractive index and low dispersion. The lens has a front and back coating of opt ir1, which is specifically designed for infrared wavelengths, enhancing its performance in the 633-1064nm range.
The lens's geometry is characterized by its edge thickness of 2.0 mm and center thickness of 2.4 mm. The inner and outer radii are both zero, indicating a uniform curvature. The back focal length (BFL) is 898.4 mm, and the effective focal length (EFL) is 900.0 mm, demonstrating a high level of precision in its design and manufacture.
This lens is available for purchase directly from the vendor's website, where it is currently in stock. Its detailed specifications, coupled with its availability, make it an excellent choice for a wide range of optical applications.
