G340160400 12.7 mm Dia. UVFS Plano-Concave Lens; EFL=-20mm
The G340160400 is a plano-concave lens with a diameter of 12.7 mm, sourced from Qioptiq Photonics. This lens is designed for use with a wavelength of 355 nm and features a fused silica material (UVFS Mal-1965) for superior optical performance. The lens has a center thickness of 4 mm and an effective focal length (EFL) of -20 mm, making it suitable for applications that require negative focal lengths.
The lens's spherical geometry is characterized by a radius of curvature (R1) of -10.002 mm for the concave surface, with the planar surface having an infinite radius. The lens does not have an inner or outer radius, indicating a uniform curvature across the lens surface.
The G340160400 lens is coated with Qio Silver RAGV 45 on both the front and back surfaces, enhancing its reflectivity and durability. This coating is designed to provide high reflectivity at the specified wavelength, making the lens ideal for use in laser applications.
The lens is currently in stock and available for purchase on the Qioptiq Photonics website. For more information, please refer to the provided weblink.
