The SLB-50-150NIR1 is a Plano-Concave Spherical Lens, designed with a diameter of 50.0 mm and a focal length of -150.0 mm. This lens is sourced from OptoSigma, a renowned vendor known for their high-quality optical elements. The lens is made from n-bk7 schott, a material widely used in optical applications due to its excellent optical properties.
The lens's geometry is meticulously crafted, with a thickness edge of 7.1 mm and a thickness center of 3 mm. The inner and outer radii are both zero, indicating a uniform curvature. The lens's effective focal length (EFL) is -150 mm, and the back focal length (BFL) is -152 mm, suggesting a concave shape.
The SLB-50-150NIR1 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 minimal reflection, making it suitable for various applications, including laser systems and imaging applications.
