SLB-10B-25N 10.0 mm Dia. x -24.7 mm FL; Double-Concave Lens Uncoated

The SLB-10B-25N is a high-quality double-concave lens offered by OptoSigma, a leading vendor in the optical industry. This lens, designed with a spherical shape, is crafted from n-BK7 Schott, a renowned optical glass known for its excellent transparency and homogeneity.

The lens boasts a diameter of 10.0 mm and a thickness of 3.0 mm at the edge, tapering down to 2.0 mm at the center. The double-concave design, characterized by radii of curvature of -25.95 mm and 25.95 mm for the first and second surfaces, respectively, results in a back focal length of -24.7 mm. This configuration is ideal for applications requiring a negative lens with a high refractive power.

The lens is uncoated, offering users the flexibility to apply their preferred coating based on their specific application requirements. However, it's crucial to note that the uncoated version may have reduced transmission and increased susceptibility to environmental factors such as dust and moisture.

This lens is designed to operate at a wavelength of 546.1 nm, making it suitable for a wide range of applications in fields such as metrology, interferometry, and beam shaping. The item data indicates that this lens is currently in stock, ensuring quick delivery for your optical project needs.
