SLB-25-60NIR2 25.0 mm Dia. x -60.0 mm FL; Coated; Plano-Concave Lens 750-1550nm
The SLB-25-60NIR2 is a Plano-Concave Spherical Lens, designed with a diameter of 25.0 mm and a focal length of -60.0 mm. This lens is sourced from OptoSigma, a renowned vendor known for their high-quality optical elements. The lens is made from n-bk7 schott, a material widely used in optical applications due to its excellent optical properties.
The lens's geometry is meticulously crafted, with an edge thickness of 4.6 mm and a center thickness of 2 mm. The lens's effective focal length (EFL) is -60.0 mm, and its front and back radii are -31.14 mm and -61.3 mm respectively. The lens's inner and outer radii are both 0 mm, indicating a uniform curvature.
The SLB-25-60NIR2 is coated with Opt IR2, a broadband anti-reflection coating that is specifically designed for the 750-1550nm wavelength range. This coating significantly reduces surface reflections, enhancing the lens's performance in the specified wavelength range.
