SLB-15-70N 15.0 mm Dia. x -70.0 mm FL; Plano-Concave Lens Uncoated
The SLB-15-70N is a Plano-Concave Lens, a type of spherical lens, sourced from OptoSigma. This lens has a base shape of a circle and is uncoated. The lens is designed for use in the visible light spectrum, specifically at a wavelength of 546.1 nm.
The lens has a diameter of 15.0 mm and a thickness at the edge of 2.8 mm. The thickness at the center is 2.0 mm. The effective focal length (EFL) of the lens is -70.0 mm, indicating that it is a diverging lens. The radius of curvature (R1) is -36.33 mm, and the back focal length (BFL) is -71.3 mm. The lens does not have an inner or outer radius.
The lens is made of n-BK7 Schott, a common optical glass. This material is known for its excellent optical properties, making it suitable for a wide range of applications. The lens is not coated, which means it does not have any anti-reflective or other surface treatments.
According to the vendor's website, the lens is in stock, indicating that it is readily available for purchase and use. The website also provides a direct link to the product page for easy access and further information.
