This is the G312361000 63 mm Dia. N-BK7 Plano-Convex Lens, a high-quality optical component sourced from Qioptiq Photonics. The lens, which is uncoated, is designed with a plano-convex geometry, featuring a flat (plano) surface on one side and a curved (convex) surface on the other.
The lens has a diameter of 63 mm and a thickness at the edge of 2.8 mm. The center thickness is 10 mm, providing a robust structure for various optical applications. The effective focal length (EFL) of this lens is 140 mm, making it suitable for systems that require a longer focal length.
The lens is made of N-BK7, a popular glass type in the optical industry due to its excellent optical properties. This material is known for its low dispersion and high Abbe number, making it an ideal choice for applications that require high image quality and color correction.
The lens's shape is spherical, a common geometry in optical systems due to its ease of manufacturing and good optical performance. The inner and outer radii of the lens are 0, indicating a plano surface on one side and a curved surface on the other with a radius of 72.862 mm.
The lens is designed to operate at a wavelength of 588 nm. It is important to note that the lens does not have any coating, which may affect its performance in certain applications. However, its uncoated nature can be beneficial in applications where anti-reflection coating is not required or desirable.
