This is the G063354331 model from Qioptiq Photonics, a 22.4 mm diameter Plano-Concave Lens with a mounted fused silica. The lens is designed with a negative focal length (EFL) of -100mm, making it suitable for applications that require light convergence.
The lens's geometry is characterized by a center thickness of 1.5mm, an inner radius of 0mm, and an outer radius of 0mm. The plano-concave shape is spherical, with a radius of curvature (R1) of -50.481mm on the concave surface. This specific curvature allows for precise light manipulation in your optical system.
The lens is made from UVFS material, identified as "UVFS mal- 1965" in the item data. This material is suitable for use in the ultraviolet region of the spectrum, specifically at a wavelength of 355nm. The lens is coated on both the front and back with Qio AL RALVIS AOI 45, a coating that enhances the lens's performance in specific applications.
The lens is mounted, which adds to its convenience and ease of use. It is currently in stock and available for purchase through the provided weblink. This lens is a reliable and high-quality choice for your optical system, offering precision and durability.
