SLSQ-25-170P 25.0 mm Dia. x 170.0 mm FL; Plano-Convex Lens Uncoated

The SLSQ-25-170P is a Plano-Convex lens with a diameter of 25.0 mm and a focal length of 170.0 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 spherical shape, with a center thickness of 3.0 mm and an edge thickness of 2.0 mm. The inner radius is 0.0 mm, and the outer radius is also 0.0 mm, indicating a uniform curvature. The effective focal length (EFL) is 170.0 mm, and the back focal length (BFL) is 167.9 mm. The radius of curvature (R1) is 78.2 mm.

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 that the lens can be used in a wider range of applications without the risk of coating interference.

The wavelength for this lens is 546.1 nm, which is within the visible light spectrum. This makes it suitable for applications that involve visible light, such as imaging systems, beam shaping, and light collimation.
