SLB-25-50NIR1 25.0 mm Dia. x -50.0 mm FL; Coated; Plano-Concave Lens 633-1064nm

The SLB-25-50NIR1 is a Plano-Concave Spherical Lens, sourced from the reputable vendor OptoSigma. This lens boasts a 25.0 mm diameter and a focal length of -50.0 mm, making it ideal for a wide range of optical applications.

The lens is crafted from n-bk7 schott, a high-quality optical glass known for its excellent transmittance and homogeneity. This material ensures the lens delivers sharp, clear images, making it suitable for use in imaging systems, beam shaping, and other applications where high-quality optical performance is required.

The lens features a double-sided coating, with both the front and back surfaces coated with opt ir1. This coating enhances the lens's performance in the 633-1064nm wavelength range, reducing reflection and increasing transmission. This makes the lens particularly suitable for use in systems operating in the near-infrared spectrum.

The lens has a center thickness of 2 mm and an edge thickness of 5.2 mm, providing a robust and durable design. The inner and outer radii are both 0 mm, indicating a flat surface on both sides of the lens. The lens's geometry is designed to provide a concave surface, ideal for use in applications where beam divergence needs to be increased or where a negative focal length is required.
