G312405000 31.5 mm Dia. N-BK7 Plano-Convex Lens; EFL=200mm Uncoated

The G312405000 is a 31.5 mm diameter Plano-Convex lens, sourced from Qioptiq Photonics, featuring a focal length of 200mm and manufactured from N-BK7 Schott glass. This lens is uncoated, offering a cost-effective solution for applications where coating is not required.

The Plano-Convex lens design consists of a flat (plano) surface and a curved (convex) surface. This particular lens has an inner radius of 0 mm and an outer radius of 0 mm, with a center thickness of 3.2 mm and an edge thickness of 2 mm. The lens's geometry is optimized for applications requiring a long focal length, making it suitable for imaging systems, beam shaping, or other optical systems where a precise, well-collimated beam is necessary.

The N-BK7 Schott glass material is a popular choice for its high homogeneity, low auto-fluorescence, and excellent transmittance in the visible and near-infrared regions. This lens is specifically designed to operate at a wavelength of 588 nm.

The uncoated surface of this lens may result in reduced transmission and increased susceptibility to environmental factors such as dirt, dust, and moisture. However, uncoated lenses are often preferred in applications where cost, simplicity, or specific optical properties are of higher importance.
