SLB-15B-20PM 15.0 mm Dia. x 20.8 mm FL; Coated; Double-Convex Lens 400-700nm
The SLB-15B-20PM is a high-quality spherical lens, specifically designed for use in the 400-700nm wavelength range. This lens, sourced from the reputable vendor OptoSigma, boasts a 15.0 mm diameter and a focal length of 20.8 mm, making it a versatile choice for a variety of optical applications.
The lens is made from n-bk7 schott, a popular material known for its excellent optical properties. This is a double-convex lens, meaning it has two convex surfaces. The first surface has a radius of curvature of 20.76 mm, while the second surface has a radius of -20.76 mm, indicating a concave shape. This particular lens design allows for a high degree of light bending, making it ideal for use in focusing or collimating light.
The lens has an edge thickness of 2 mm and a center thickness of 4.8 mm, providing robustness and durability. The back and front surfaces of the lens are coated with an opt m coating, which enhances its transmission capabilities and protects it from environmental factors.
The SLB-15B-20PM is currently in stock and available for immediate purchase. For more information, please refer to the vendor's website or contact their sales team directly.
