The SLSQ-10-25P is a Plano-Convex Lens, sourced from OptoSigma, a renowned vendor in the optical industry. This lens is characterized by its spherical shape and circular base, with a diameter of 10.0 mm and a thickness that varies from 2.0 mm at the edge to 3.1 mm at the center.
The lens is designed with a focal length (FL) of 25.0 mm, which is the distance from the lens's center to the point where light rays converge or diverge. The back focal length (BFL) of this lens is 22.8 mm, which is the distance from the lens's rear surface to the point where the light rays converge or diverge.
The lens is made of fused silica, a high-quality material known for its excellent optical properties and durability. The material's index of refraction at the specified wavelength of 546.1 nm is not provided, but it can be assumed to be around 1.46, a typical value for fused silica.
Notably, this lens is uncoated, meaning it does not have any anti-reflective or other coatings applied to its surfaces. This may result in higher reflective losses and lower transmission, but it also means the lens is less prone to damage and contamination.
