The SLB-40-60NIR1 is a Plano-Concave Spherical Lens, 40.0 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 includes a thickness edge of 9.3 mm and a thickness center of 2 mm, providing a balanced structure for various applications. The effective focal length (EFL) is -60.0 mm, indicating a concave lens that diverges light. The front and back radii are -31.14 mm and -61.3 mm, respectively, contributing to the lens's overall optical performance.
The SLB-40-60NIR1 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 transmission and reduces reflection, making it suitable for use in near-infrared (NIR) applications.
