SLSQ-50-120N 50.0 mm Dia. x -120.0 mm FL; Plano-Concave Lens Uncoated

The SLSQ-50-120N 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 base shape of a circle and is uncoated.

The lens's geometry is characterized by its edge thickness of 9.0 mm and center thickness of 3.0 mm. The effective focal length (EFL) is -120.0 mm, indicating its concave nature. The radius of curvature (R1) is -55.2 mm, and the back focal length (BFL) is -122.1 mm. The lens is made of fused silica, a material known for its high transparency and resistance to thermal shock.

The lens is designed to operate at a wavelength of 546.1 nm. It is important to note that the lens does not have any coating, which may affect its performance in certain applications. However, its uncoated nature can make it more cost-effective and suitable for applications where coating is not necessary.

The lens's web link status is valid and it is currently in stock, making it readily available for immediate use. This lens is a great option for those needing a high-quality, negative focal length lens for their optical system.
