SLB-30-900PIR1 30.0 mm Dia. x 900.0 mm FL; Coated; Plano-Convex Lens 633-1064nm

The SLB-30-900PIR1 is a Plano-Convex Spherical Lens, sourced from OptoSigma, with a diameter of 30.0 mm and a focal length of 900.0 mm. This lens is made of n-bk7 schott material, a popular choice for its high refractive index and low dispersion. The lens's geometry includes a 2.0 mm thickness at the edge and a 2.2 mm thickness at the center, contributing to its robustness and durability.

The lens's front and back surfaces are coated with opt ir1, a coating that enhances its performance in the infrared spectrum, specifically between 633nm and 1064nm. This coating ensures optimal transmission and reduces reflection, making it suitable for applications that require high-quality imaging or light transmission in the infrared range.

The lens's base shape is circular, and its geometry is spherical, which is a common choice for its ease of manufacturing and versatility in various applications. The lens's inner and outer radii are 0, indicating a uniform curvature across the lens surface.

The lens's EFL (Effective Focal Length) is 900.0 mm, and its R1 (Radius of Curvature of the First Surface) is 467.1 mm. The BFL (Back Focal Length) is 898.5 mm, which is a critical parameter for designing optical systems.
