L-BCC115 50 mm Dia. Double-Concave Lens; EFL=-500mm Uncoated
The L-BCC115 is a 50 mm diameter Double-Concave Spherical Lens, sourced from the renowned optical vendor, Ross Optical. This lens is designed with a base shape of a circle, and its concave-concave structure is specifically engineered for spherical geometry.
The lens features an effective focal length (EFL) of -500mm, indicating its diverging nature. This means that it spreads out light rays, making it ideal for applications such as beam expansion or correction of diverging light.
The L-BCC115 has a center thickness of 2.5mm and an edge thickness of 3.7mm, providing a robust and durable structure. The lens is uncoated, offering a clear and transparent optical path without any additional anti-reflective or protective coatings.
This lens is made from N-BK7 Schott, a high-quality optical glass known for its excellent optical properties and chemical durability. It is designed to work optimally at a wavelength of 587.6nm, making it suitable for a wide range of applications in the visible light spectrum.
