SLB-50.8-300NIR1 50.8 mm Dia. x -300.0 mm FL; Coated; Plano-Concave Lens 633-1064nm

The SLB-50.8-300NIR1 is a Plano-Concave Spherical Lens, 50.8 mm in diameter, with a focal length of -300.0 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 features a front and back coating of opt ir1, which is specifically designed for use in the 633-1064nm wavelength range. This coating enhances the lens' performance in this spectral region, making it ideal for applications that require high-quality optical components in the near-infrared spectrum.

The geometry of the lens includes a thickness edge of 5.1 mm and a thickness center of 3 mm. The inner and outer radii are both 0 mm, indicating a uniform curvature across the lens. The back focal length (bfl) is -302 mm, slightly longer than the effective focal length (efl) of -300 mm.

This lens is part of the Spherical Lens (Plano-Concave) subtype, which is characterized by one side being flat and the other side being concave. This design is often used in optical systems where a reduction in the size of the beam or the divergence of the beam is required.
