The SLB-15-120PIR1 is a Plano-Convex Spherical Lens, 15.0 mm in diameter and 120.0 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, with a 2.0 mm edge thickness and a 2.5 mm center thickness. The front and back surfaces of the lens are coated with opt ir1, a coating designed to enhance performance in the infrared spectrum, specifically between 633-1064nm. This coating ensures optimal transmission and reduces reflection, making the lens suitable for use in IR imaging systems, spectroscopy, and other applications where high-quality transmission in the infrared region is required.
The lens has an effective focal length (EFL) of 120.0 mm and a back focal length (BFL) of 118.4 mm. The inner and outer radii are 0 mm, indicating a uniform curvature across the lens surface. The lens's shape is spherical, a common choice for its simplicity and versatility.
