SLSQ-25.4-40P 25.4 mm Dia. x 40.0 mm FL; Plano-Convex Lens Uncoated

The SLSQ-25.4-40P is a Plano-Convex lens with a diameter of 25.4 mm and a focal length of 40.0 mm, sourced from the reputable vendor 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 geometry is characterized by its edge thickness of 1.8 mm and center thickness of 6.9 mm. The effective focal length (EFL) is 40 mm, and the radius of curvature (R1) is 18.4 mm. The back focal length (BFL) is 35.3 mm, and the lens has no inner or outer radius, indicating a flat surface on the non-curved side.

The SLSQ-25.4-40P is uncoated, meaning it does not have any additional layers to enhance its optical properties. This may make it more susceptible to environmental factors such as dust and moisture, but it can also make it more cost-effective.

This lens is designed for use at a wavelength of 546.1 nm, making it suitable for a wide range of applications in the visible light spectrum. Its spherical shape ensures a high level of optical performance, making it a reliable choice for various optical systems.
