SLB-25-200P 25.0 mm Dia. x 200.0 mm FL; Plano-Convex Lens Uncoated

The SLB-25-200P is a Plano-Convex lens with a diameter of 25.0 mm and a focal length of 200.0 mm. This lens is sourced from OptoSigma, a renowned vendor in the optical industry. The lens is made of n-BK7 Schott, a high-quality optical glass known for its excellent transparency and low auto-fluorescence.

The lens geometry is characterized by its spherical shape, with a radius of curvature (R1) of 103.8 mm for the convex surface. The lens has an effective focal length (EFL) of 200.0 mm and a back focal length (BFL) of 198.2 mm. The thickness at the edge of the lens is 2.0 mm, while the center thickness is 2.8 mm. The lens is uncoated, offering a clear, unaltered view of the light path but without any additional protection or enhancement.

This lens is suitable for a wide range of applications, including imaging, beam shaping, and laser applications. The uncoated surface allows for high transmission across the visible spectrum, making it ideal for use with broadband light sources. However, it may be more susceptible to damage from laser light or environmental factors compared to coated lenses.

Please note that the lens data is provided for the d-line (546.1 nm). For other wavelengths, the parameters may vary slightly. Always consult the vendor or use optical design software to ensure the lens meets your specific requirements.
