SLB-30-40NIR2 30.0 mm Dia. x -40.0 mm FL; Coated; Plano-Concave Lens 750-1550nm
The SLB-30-40NIR2 is a Plano-Concave Spherical Lens, sourced from the renowned optical component manufacturer, OptoSigma. This lens, with a diameter of 30.0 mm and a focal length of -40.0 mm, is designed for use within the wavelength range of 750-1550nm, making it suitable for near-infrared applications.
The lens is crafted from the high-quality material, n-bk7 schott, which is known for its excellent optical properties. The base shape of the lens is circular, and it features a planar surface on one side and a concave surface on the other. The edge thickness of the lens is 8.4 mm, while the center thickness is 2 mm, providing a robust structure.
The lens comes with a broadband anti-reflection coating, specifically the opt ir2 coating, on both the front and back surfaces. This coating enhances the lens' performance by reducing surface reflections, thereby increasing transmission and minimizing losses. The coating is designed to work within the same wavelength range as the lens, ensuring optimal performance.
