SLSQ-25.4-100N 25.4 mm Dia. x -100.0 mm FL; Plano-Concave Lens Uncoated

OptoSigma's SLSQ-25.4-100N is a plano-concave lens made of fused silica, a material known for its excellent optical properties and high damage threshold. This lens has a diameter of 25.4 mm and a focal length of -100.0 mm, making it suitable for applications that require a long focal length and a wide field of view.

The lens's geometry is characterized by its base shape, which is circular, and its thickness. The edge thickness is 3.8 mm, while the center thickness is 2 mm. The lens's inner and outer radii are both 0 mm, indicating a flat surface on one side and a concave surface on the other. The radius of curvature of the concave surface is -46 mm.

The SLSQ-25.4-100N is uncoated, which means it does not have any anti-reflective or other coatings. This can be advantageous in some applications where the uncoated surface provides the desired optical properties. However, it also means that the lens may have higher reflectivity and be more susceptible to damage from laser light.

The lens is designed to work at a wavelength of 546.1 nm, which is in the green part of the spectrum. This wavelength is commonly used in applications such as fluorescence microscopy and interferometry.
