SLSQ-25.4-200P 25.4 mm Dia. x 200.0 mm FL; Plano-Convex Lens Uncoated

The SLSQ-25.4-200P is a Plano-Convex lens with a diameter of 25.4 mm and a focal length of 200.0 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 1.9 mm and center thickness of 2.9 mm. The effective focal length (EFL) is 200 mm, and the radius of curvature (R1) is 92 mm. The back focal length (BFL) is 198 mm, and both the inner and outer radii are 0 mm.

This lens is uncoated, meaning it does not have any additional layers to enhance its optical properties. However, uncoated lenses can still provide high-quality imaging, especially in applications where the light source has a narrow spectral bandwidth, such as monochromatic light.

The SLSQ-25.4-200P is designed for use at a wavelength of 546.1 nm. It is a spherical lens, which means it has a curved surface that is a section of a sphere. This type of lens is commonly used in various optical systems due to its simple design and versatility.
