SLSQ-07B-40P 7.0 mm Dia. x 40.3 mm FL; Double-Convex Lens Uncoated
The SLSQ-07B-40P is a 7.0 mm diameter, double-convex lens with a focal length of 40.3 mm, sourced from OptoSigma. This lens is made of fused silica, a material known for its excellent optical properties, including high transparency and resistance to thermal shock.
The lens features a convex-convex geometry, with both surfaces curved outward. The first surface has a radius of curvature of 36.8 mm, while the second surface has a radius of -36.8 mm, indicating a steeper curvature. This geometry results in a back focal length of 39.7 mm and an effective focal length of 40.3 mm.
The lens has a thickness of 1.6 mm at the edge and 1.9 mm at the center. Notably, it is uncoated, meaning it does not have any anti-reflective or other coatings. This may result in higher reflective losses, but it also means the lens can be used in a wider range of wavelengths without the risk of coating damage.
The SLSQ-07B-40P is currently in stock and can be purchased directly from the OptoSigma website. With its high-quality fused silica material and precise double-convex geometry, this lens is suitable for a wide range of optical applications.
