SLSQ-20-50P 20.0 mm Dia. x 50.0 mm FL; Plano-Convex Lens Uncoated

The SLSQ-20-50P is a Plano-Convex lens with a diameter of 20.0 mm and a focal length of 50.0 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 a convex surface with a radius of curvature of 23.0 mm, and a thickness of 2.0 mm at the edge, increasing to 4.3 mm at the center. The effective focal length (EFL) is 50.0 mm, and the back focal length (BFL) is 47.1 mm. The lens is uncoated, offering bare optics for applications where coating is not required or preferred.

This lens is suitable for a wide range of applications, including imaging, beam shaping, and laser applications. The uncoated surface can be advantageous in applications where anti-reflection coating is not necessary, reducing cost and complexity. However, for applications where high transmission and low reflection are required, coated versions of this lens are available from OptoSigma.

Please note that the wavelength for this lens is 546.1 nm, and it is spherical in shape. The lens is circular, making it compatible with various optical systems. The lens data is valid and in stock, ensuring prompt delivery upon order.
