SLB-25-30NIR2 25.0 mm Dia. x -30.0 mm FL; Coated; Plano-Concave Lens 750-1550nm
The SLB-25-30NIR2 is a Plano-Concave Spherical Lens, 25.0 mm in diameter and featuring a focal length of -30.0 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's geometry includes an edge thickness of 8.3 mm and a center thickness of 2 mm. The effective focal length (EFL) is -30.0 mm, and the radius of curvature (R1) is -15.57 mm. The back focal length (BFL) is -31.3 mm, and both the inner and outer radii are 0 mm.
The SLB-25-30NIR2 is coated with opt ir2 on both the front and back surfaces, making it suitable for use within the wavelength range of 750-1550nm. This coating enhances the lens's performance by reducing reflection and increasing transmission, thereby improving the overall efficiency and quality of the optical system in which it is used.
