SLB-10-90N 10.0 mm Dia. x -90.0 mm FL; Plano-Concave Lens Uncoated

The SLB-10-90N is a Plano-Concave Lens, part of the Spherical Lens category, sourced from the reputable vendor OptoSigma. This lens is characterized by its circular base shape and uncoated surface, offering a high-quality, cost-effective solution for various optical applications.

The lens has a diameter of 10.0 mm, providing a substantial surface area for light transmission. The edge thickness is 2.3 mm, and the center thickness is 2.0 mm, ensuring robustness and durability. The effective focal length (EFL) of this lens is -90.0 mm, indicating its concave nature, which is further emphasized by its radius of curvature (R1) of -46.71 mm.

The lens is made from n-BK7 Schott, a popular optical glass due to its excellent optical properties and versatility. It is designed to work optimally with a wavelength of 546.1 nm, making it suitable for a wide range of applications, from imaging to laser systems.

The lens is uncoated, offering a more affordable option for users who do not require the additional light control and scratch resistance provided by coatings. However, this does mean that the lens may be more susceptible to environmental damage and may not perform as well in high-intensity light applications.
