SLB-25B-150PM 25.0 mm Dia. x 150.5 mm FL; Coated; Double-Convex Lens 400-700nm
The SLB-25B-150PM is a high-quality lens from OptoSigma, designed for use in the 400-700nm wavelength range. This lens is a spherical, biconvex design, made from n-bk7 schott material, which is known for its excellent optical properties.
The lens has a diameter of 25.0 mm and a focal length of 150.5 mm, making it suitable for a wide range of applications. The edge thickness of the lens is 2.0 mm, while the center thickness is 3.0 mm, providing a robust and durable design. The lens features a broadband anti-reflection coating on both the front and back surfaces, which enhances its transmission capabilities and reduces unwanted reflections.
The geometry of the lens is designed to provide superior optical performance. The first radius of curvature (r1) is 155.7 mm, while the second radius (r2) is -155.7 mm. The back focal length (bfl) is 149.5 mm, and the lens has no inner or outer radius, ensuring a clear and undistorted optical path.
