SLB-15-60N 15.0 mm Dia. x -60.0 mm FL; Plano-Concave Lens Uncoated

The SLB-15-60N is a Plano-Concave Lens with a 15.0 mm diameter and a focal length of -60.0 mm. This lens is sourced from OptoSigma, a renowned vendor in the optical industry. The lens is made of n-BK7 Schott material, a popular choice for its high refractive index and low dispersion.

The lens geometry is characterized by its spherical shape, with a center thickness of 2.0 mm and an edge thickness of 2.9 mm. The inner and outer radii are both 0 mm, indicating a flat surface on one side and a concave surface on the other. The back focal length (BFL) is -61.3 mm, slightly longer than the specified focal length due to the thickness of the lens.

This lens is uncoated, meaning it does not have any additional layers to enhance its optical properties. While this may result in a lower transmission rate and a higher susceptibility to environmental factors, it also means that the lens can be used in a wider range of applications without the risk of coating interference.

The lens is designed to operate at a wavelength of 546.1 nm, making it suitable for use in applications that require high precision and accuracy, such as metrology, interferometry, and beam shaping.
