This is a Plano-Convex lens, sourced from Qioptiq Photonics, with a diameter of 25.4 mm and a focal length of 150 mm at a wavelength of 1064 nm. The lens is made of N-BK7, a popular glass type in the optical industry known for its excellent optical properties, high transmittance in the visible and near-infrared regions, and low auto-fluorescence.
The lens has a front coating of Qio HP Nbar ARHS-YAG and a back coating of the same, providing anti-reflection properties and ensuring high transmission of light. The edge thickness of the lens is 3 mm, while the center thickness is 4 mm, providing a good balance between weight and optical performance.
The lens is spherical in shape, which is a common geometry for optical lenses due to its ease of manufacturing and good optical performance. The inner radius of the lens is 0, and the outer radius is also 0, indicating that the lens is a simple plano-convex design.
The lens is available for purchase from the Qioptiq Photonics website, where you can find more detailed specifications and purchasing information. The link to the product page is provided in the item data for your convenience.
