SLB-15-70P 15.0 mm Dia. x 70.0 mm FL; Plano-Convex Lens Uncoated

The SLB-15-70P is a Plano-Convex lens with a diameter of 15.0 mm and a focal length of 70.0 mm. This lens is sourced from OptoSigma, a renowned vendor in the optical industry. The lens is made of n-BK7 Schott, a high-quality optical glass known for its excellent transparency and low auto-fluorescence.

The lens geometry includes a thickness edge of 2.0 mm and a thickness center of 2.8 mm. The effective focal length (EFL) is 70.0 mm, and the radius of curvature (R1) is 36.33 mm. The back focal length (BFL) is 68.2 mm, and both the inner and outer radii are 0 mm, indicating a flat surface on the non-curved side of the lens.

This lens is uncoated, meaning it does not have any anti-reflective or other coatings applied to its surfaces. While this may result in a higher reflectivity at the air-glass interface, it also means the lens can be used in a wider range of applications without the risk of coating-specific limitations.

The lens is designed for a wavelength of 546.1 nm, making it suitable for use in applications that use this wavelength, such as certain types of fluorescence microscopy. The lens shape is spherical, which is a common and versatile lens shape in many optical applications.
