The SLB-15-30N is a Plano-Concave Lens with a 15.0 mm diameter and a focal length of -30.0 mm. This lens is sourced from OptoSigma, a renowned vendor in the optical industry, and is uncoated. The lens is made of n-BK7 Schott material, a popular choice for its high refractive index and low dispersion.
The lens's geometry is characterized by its diameter of 15.0 mm, a thickness of 3.9 mm at the edge, and 2.0 mm at the center. 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 -31.3 mm, and the effective focal length (EFL) is -30.0 mm.
This lens is designed for use in monochromatic applications at a wavelength of 546.1 nm. Its spherical shape allows for a wide range of optical applications, making it a versatile choice for various projects.
Please note that the lens is uncoated, which may affect its performance in certain applications. Coatings can be added to enhance the lens's durability, reduce reflection, or alter its optical properties. However, this particular lens is supplied without any coating.
