SLSQ-50.8B-250P 50.8 mm Dia. x 251.0 mm FL; Double-Convex Lens Uncoated

OptoSigma's SLSQ-50.8B-250P is a high-quality, double-convex lens made from fused silica, a material known for its excellent optical properties and durability. This lens boasts a diameter of 50.8 mm and a focal length of 251.0 mm, making it suitable for a wide range of optical applications.

The lens is uncoated, which means it does not have any additional layers to enhance light transmission or reduce reflection. However, this does not compromise its performance, as fused silica inherently has a low refractive index and minimal absorption across a broad spectrum of wavelengths.

The geometry of the lens is defined by its double-convex shape, with radii of curvature of 230 mm for the first surface and -230 mm for the second surface. This shape allows for efficient light bending and focusing, making the lens ideal for use in imaging systems, beam shaping, and other applications where precise light control is required.

The lens has a central thickness of 5.8 mm and an edge thickness of 3 mm, providing structural integrity and resistance to deformation. The inner and outer radii are both 0 mm, indicating a uniform curvature across the lens surface.

This lens is designed to work with a wavelength of 546.1 nm, a common reference wavelength in optical systems. It is important to note that the performance of the lens can vary depending on the wavelength of the light it is intended to transmit or focus.
