This is the PLCX-50.8-257.5-UV, a Plano-Convex Spherical Lens with a diameter of 50.8 mm, sourced from CVI Laser Optics. The lens is designed for use with a wavelength of 266 nm and is uncoated.
The lens's geometry is characterized by its edge thickness of 5.1 mm and center thickness of 6.4 mm. The effective focal length (EFL) is 515.3 mm, making it suitable for a variety of optical applications. The lens's curvature is defined by a radius (R1) of 257.5 mm, with no inner or outer radius specified.
The lens is made from UVFS material, specifically identified as "UVFS MAL-1965". This material is often used in laser applications due to its transparency in the ultraviolet spectrum. The lens is uncoated, which means it does not have any additional layers to enhance its optical properties or protect it from environmental factors.
The lens's catalog number is PLCX-50.8-257.5-UV, and it is currently in stock.
