This is the G052311000 12.7 mm Dia. N-BK7 Mounted Plano-Concave Lens, a high-quality optical component sourced from Qioptiq Photonics. The lens, which has a negative focal length (EFL) of -500mm, is designed for use in a wide range of optical systems and applications.
The lens is made from N-BK7, a popular borosilicate glass known for its excellent optical properties. This material is often used in high-precision applications due to its low coefficient of thermal expansion and high transmittance across a broad spectrum. The lens's geometry includes a 12.7 mm diameter and a center thickness of 1.5 mm, making it suitable for use in systems with limited space.
The Plano-Concave design of this lens, where one surface is flat and the other is curved inward, allows for the manipulation of light in specific ways. This design is often used in applications where light needs to be spread out over a larger area or where a reduction in the overall optical power of a system is required.
Notably, this lens is uncoated. While coatings can be used to enhance the performance of optical components by reducing reflections, increasing transmission, or providing other benefits, an uncoated lens can be advantageous in certain situations. For instance, uncoated lenses can be more cost-effective and are often more resistant to damage from environmental factors.
