SLSQ-25.4-250P 25.4 mm Dia. x 250.0 mm FL; Plano-Convex Lens Uncoated

The SLSQ-25.4-250P is a Plano-Convex lens with a diameter of 25.4 mm and a focal length of 250.0 mm, making it ideal for a wide range of optical applications. This lens is sourced from OptoSigma, a renowned vendor in the optical industry, and is available in their online catalog.

The lens is made of fused silica, a material known for its excellent optical properties, including high transparency and resistance to thermal shock. The Plano-Convex geometry, where one side is flat and the other is curved, is a common choice in optical systems due to its simplicity and versatility.

The SLSQ-25.4-250P has a center thickness of 2.7 mm and an edge thickness of 1.9 mm, providing a good balance between optical performance and mechanical robustness. The lens's effective focal length (EFL) is 250 mm, and its back focal length (BFL) is 248.2 mm. The inner and outer radii are both 0 mm, indicating a sharp curvature on the convex side.

This lens is uncoated, meaning it does not have any additional layers to enhance its optical properties. While this may result in a lower transmission rate and increased susceptibility to environmental factors, it also means the lens can be used in a wider range of wavelengths without the risk of coating damage.
