L-PCC011 12.5 mm Dia. Plano-Concave Lens; EFL=-20mm Uncoated
The L-PCC011 is a plano-concave lens with a diameter of 12.5 mm, making it a compact yet powerful optical component. This lens is manufactured by Ross Optical, a reputable vendor known for its high-quality optical elements. The lens is designed with a center thickness of 1.5 mm, providing a balance between durability and weight.
The L-PCC011 has an effective focal length (EFL) of -20 mm, indicating its concave nature. This negative focal length allows the lens to diverge light, making it ideal for applications such as beam expansion or collimation. The lens's concave shape is further defined by its radius of curvature (R1), which is -10.336 mm.
This lens is made from N-BK7 Schott glass, a popular material due to its excellent optical properties and high Abbe number. The wavelength for this lens is 587.6 nm, which falls within the visible light spectrum. The lens's spherical shape ensures consistent optical performance across the entire surface.
Notably, this lens is uncoated. While coatings can enhance optical performance by reducing reflections or increasing transmission, an uncoated lens can be advantageous in certain applications where cost, simplicity, or specific optical characteristics are priorities.
