SLB-50-120NM 50.0 mm Dia. x -120.0 mm FL; Coated; Plano-Concave Lens 400-700nm

The SLB-50-120NM is a Plano-Concave Spherical Lens, sourced from OptoSigma, a renowned vendor in the optical industry. This lens boasts a diameter of 50.0 mm and a focal length of -120.0 mm, making it a versatile component for various optical applications.

The lens is crafted from n-bk7 schott, a high-quality optical glass known for its excellent transmittance and homogeneity. This material is particularly suitable for applications in the visible spectrum, as indicated by the lens's specified wavelength of 546.1 nm.

The SLB-50-120NM features a Coated surface finish on both the front and back, enhancing its overall light transmission capabilities. The coating, identified as 'opt m', is specifically designed to optimize performance within the 400-700 nm range, aligning with the lens's intended use in visible light applications.

The lens's geometry is defined by its edge thickness of 8.2 mm and center thickness of 3 mm. The inner and outer radii are both 0 mm, indicating a flat surface on one side and a concave surface on the other. The back focal length (BFL) is -122 mm, slightly exceeding the specified focal length due to the lens's concave shape.
