G063871000 25.4 mm Dia. N-BK7 Mounted Plano-Concave Lens; EFL=-50mm Uncoated
This is a 25.4 mm diameter Plano-Concave lens, manufactured by Qioptiq Photonics, featuring a negative focal length (EFL) of -50mm. The lens is made of N-BK7, a popular glass type in the optical industry, known for its excellent optical properties and versatility.
The lens's geometry is characterized by a center thickness of 1.5mm, an inner radius of 0mm, and an outer radius of 0mm. The plano-concave shape, where one surface is flat and the other is curved, is designed to diverge light rays. This makes it ideal for applications such as beam expanders, collimators, or other systems where light needs to be spread out.
The lens is uncoated, meaning it does not have any additional layers to enhance its optical properties. While this may result in a slightly lower transmission rate and increased susceptibility to environmental factors, it also means the lens is more cost-effective and suitable for applications where such considerations are not critical.
