SLB-25.4-70NIR2 25.4 mm Dia. x -70.0 mm FL; Coated; Plano-Concave Lens 750-1550nm

The SLB-25.4-70NIR2 is a Plano-Concave Spherical Lens, designed with a diameter of 25.4 mm and a focal length of -70.0 mm. This lens is sourced from OptoSigma, a renowned vendor in the optical industry, and is available for immediate purchase.

The lens is made from n-bk7 schott, a high-quality material known for its excellent optical properties. It has a central thickness of 2 mm and an edge thickness of 4.3 mm, providing a robust structure that can withstand typical handling and usage. The lens's design includes an inner radius of 0 mm and an outer radius of 0 mm, contributing to its spherical shape.

The SLB-25.4-70NIR2 is coated with Opt IR2 on both the front and back surfaces. This coating enhances the lens's performance in the 750-1550nm wavelength range, making it suitable for various applications within this spectrum.

This lens is a Plano-Concave design, meaning it has at least one flat (Plano) surface and one curved (Concave) surface. This design is often used in optical systems to diverge or spread out light rays, making it ideal for applications such as beam expansion or collimation.
