PLCC-25.4/412.1C 25.4 mm Dia. N-BK7 Plano-Concave Lens; EFL=-800mm Uncoated

This is a Plano-Concave Lens from Laser Components, featuring a 25.4 mm diameter and a center thickness of 2 mm. The lens is made of N-BK7 Schott, a popular optical glass due to its excellent optical properties and high transmittance in the visible and near-infrared regions. The lens has a focal length (EFL) of -800mm, making it suitable for applications that require strong diverging lenses.

The lens's geometry includes a plano surface on one side and a concave surface on the other, with a radius of curvature (R1) of -412.1 mm. The inner and outer radii are both 0, indicating a simple, two-surface design. The lens is uncoated, meaning it does not have any additional layers to enhance its optical properties. However, uncoated lenses can still provide good performance for many applications, especially when the light source is not highly coherent or when the system is not very sensitive to reflections.

This lens is sourced from Laser Components, a reputable vendor known for their high-quality optical components. According to the vendor, the lens is in stock and the associated web link is valid. This information suggests that the lens is readily available for purchase and delivery.
