SLB-15-60NIR1 15.0 mm Dia. x -60.0 mm FL; Coated; Plano-Concave Lens 633-1064nm
The SLB-15-60NIR1 is a Plano-Concave Spherical Lens, 15.0 mm in diameter and featuring a focal length of -60.0 mm. This lens is sourced from OptoSigma, a renowned vendor in the optical industry. The lens is made of n-bk7 schott, a high-quality material known for its excellent optical properties.
The lens's geometry is meticulously designed, with an edge thickness of 2.9 mm and a center thickness of 2 mm. The back focal length (bfl) is -61.3 mm, and the inner and outer radii are both 0 mm, indicating a uniform curvature. The lens's effective focal length (efl) is -60 mm, which is a crucial parameter in determining the lens's optical performance.
The SLB-15-60NIR1 is coated with opt ir1 on both the front and back surfaces, enhancing its performance in the 633-1064nm wavelength range. This coating ensures optimal light transmission and reduces unwanted reflections, making the lens suitable for various applications, including but not limited to, laser systems, imaging systems, and beam shaping applications.
