This is the PLCX-25.4-30.9-C, a Plano-Convex Laser Grade Spherical Lens, sourced from CVI Laser Optics. The lens boasts a 25.4 mm diameter and is made from N-BK7 Schott, a popular material for its excellent optical properties. The lens is uncoated, which means it does not have any additional layers to enhance its optical performance.
The lens has a focal length (EFL) of 60mm, making it suitable for a variety of applications that require a longer focal length. The plano-convex design, where one side is flat and the other is curved, allows for efficient light collection and focusing. The radius of curvature of the curved side is 30.9 mm.
The lens has a thickness of 1.5 mm at the edge and 4.2 mm at the center. This variation in thickness is due to the curvature of the lens. The lens's geometry is circular, making it compatible with a wide range of optical systems.
The lens is in stock and available for immediate purchase. For more detailed specifications, please refer to the vendor's catalog, which can be found at https://www.idexot.com/media/wysiwyg/cms-pages/pdf/2-Spherical_Lenses.pdf.
