63-812 25mm Dia. x 150mm FL VIS-NIR Coated; UV Plano-Convex Lens VIS-NIR 400-1000nm

This 63-812 UV Plano-Convex Lens, sourced from Edmund Optics, is a high-quality optical component designed for use within the visible to near-infrared (VIS-NIR) spectrum, specifically covering the wavelength range of 400-1000nm. Its primary purpose is to bend light and bring it to a focus, making it an essential element in various optical systems.

The lens boasts a diameter of 25mm and a focal length of 150mm, yielding an f-number of 6. The plano-convex design features a flat front surface and a curved back surface, with a radius of curvature of 68.79mm. This particular lens has an edge thickness of 2.04mm and a center thickness of 3.18mm, ensuring durability and resistance to damage.

The lens material is fused silica (mal-1965), a low-autofluorescence material that is highly transparent in the VIS-NIR range. This makes the lens suitable for applications that require low background noise and high transmission, such as spectroscopy, interferometry, and beam shaping.

The front and back surfaces of the lens are coated with the EDM VIS-NIR 0SP 200-2000 multilayer coating, which is designed to enhance the lens's performance in the VIS-NIR spectrum. This coating reduces reflection and increases transmission, thereby improving the overall efficiency of the optical system.
