G312331000 18 mm Dia. N-BK7 Plano-Convex Lens; EFL=30mm Uncoated
This is a Plano-Convex lens with a diameter of 18 mm, sourced from Qioptiq Photonics. 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 has a focal length (EFL) of 30 mm, making it suitable for a wide range of applications.
The lens's geometry is characterized by its edge thickness of 1.7 mm and center thickness of 4.5 mm. The base shape is circular, and the lens is uncoated. The inner and outer radii are both zero, indicating a simple plano-convex design.
The lens is designed to operate at a wavelength of 588 nm. It is spherical in shape, a common choice for its ease of manufacturing and good optical performance. The lens is uncoated, which means it does not have any anti-reflective or other coatings. This may result in higher reflective losses but can be beneficial in certain applications where coatings may introduce unwanted effects.
The lens is currently in stock and can be purchased directly from the Qioptiq Photonics website. For more information, please refer to the provided weblink.
