SLSQ-40-120N 40.0 mm Dia. x -120.0 mm FL; Plano-Concave Lens Uncoated

OptoSigma's SLSQ-40-120N is a fused silica plano-concave lens, uncoated and designed for general use. This lens boasts a diameter of 40.0 mm and a focal length of -120.0 mm, making it suitable for a wide range of applications.

The lens's geometry is characterized by a thickness edge of 5.8 mm and a thickness center of 2 mm, with an inner radius of 0 mm and an outer radius of 0 mm. The concave surface of the lens has a radius of curvature (R1) of -55.2 mm, and the back focal length (BFL) is -121.4 mm.

The lens is made of fused silica, a material known for its excellent optical properties, including high transparency, low autofluorescence, and high resistance to thermal shock and chemical etching. The material ID for this lens is "fused sil mal-1965".

The lens is uncoated, meaning it does not have any additional layers to enhance its optical properties. However, uncoated lenses can be advantageous in certain applications due to their lower cost and simpler manufacturing process.

This lens is designed to work with a wavelength of 546.1 nm, making it suitable for use in a variety of optical systems. It is spherical in shape, a common and versatile geometry in optical lenses.
