LP11-06-10 6 mm Dia. N-BK7 Plano-Concave Lens; EFL=-10mm Uncoated

This product is a Plano-Concave lens, offered by CeNing Optics, with a diameter of 6 mm and a center thickness of 2 mm. The lens is made of N-BK7, a popular glass type in the optical industry, known for its excellent optical properties and wide transparency range. The effective focal length (EFL) of this lens is -10 mm, indicating that it is a diverging lens, causing incoming light rays to spread out.

The lens's geometry is defined by its inner and outer radii. In this case, the inner radius is 0, and the outer radius is also 0, suggesting that the lens has a flat outer surface and a curved inner surface. The curvature of the inner surface is specified by a radius of -5.18 mm, which is the radius of curvature for a concave surface.

This lens is designed to operate at a wavelength of 546.1 nm, which is a common reference wavelength in the optical industry. It is uncoated, meaning it does not have any anti-reflective or other coatings applied to its surfaces. This may result in higher reflective losses and a lower overall transmission compared to coated lenses.
