The SLB-25.4-90PIR1 is a Plano-Convex Spherical Lens, 25.4 mm in diameter and 90.0 mm in focal length, sourced from OptoSigma. This lens is made of n-bk7 schott material, a popular choice for its high refractive index and low dispersion, making it ideal for a wide range of optical applications.
The lens features a Plano-Convex geometry, where one side is flat (Plano) and the other side is curved (Convex). This design allows for efficient light gathering and focusing, making it suitable for use in imaging systems, beam shaping, and other applications where precise light control is required.
The lens has a diameter of 25.4 mm and a thickness of 1.9 mm at the edge, increasing to 3.7 mm at the center. The Effective Focal Length (EFL) is 90 mm, and the Radius of Curvature (R1) is 46.71 mm. The Back Focal Length (BFL) is 87.6 mm, and both the Inner and Outer Radius are 0 mm.
The lens is coated with opt ir1 on both the front and back surfaces, enhancing its performance in the infrared spectrum, specifically between 633 and 1064 nm. This coating improves the lens's durability, resistance to environmental factors, and overall light transmission, making it an excellent choice for applications in this spectral range.
