SLSQ-50-220N 50.0 mm Dia. x -220.0 mm FL; Plano-Concave Lens Uncoated
The SLSQ-50-220N is a Plano-Concave Lens, a type of spherical lens, sourced from OptoSigma. This lens, with a diameter of 50.0 mm, is designed for use in systems where a negative focal length is required. The lens has a significant concave shape, with a center thickness of 3.0 mm and an edge thickness of 6.1 mm, contributing to its negative focal length of -220.0 mm.
The lens is made of fused silica, a material known for its high transparency and resistance to thermal shock. This makes it an ideal choice for applications that require a lens with excellent optical quality and durability. The lens is uncoated, meaning it does not have any additional layers to enhance its optical properties or protect it from environmental factors.
The SLSQ-50-220N is designed to operate at a wavelength of 546.1 nm, a common wavelength for many optical systems. It is important to note that the lens's performance may vary depending on the wavelength of the light it is intended to focus.
