The ultraviolet fused silica positive meniscus lens is a precision optical element specially designed for optical systems in the ultraviolet to near-infrared bands. The lens is made of high-purity UV fused silica, which has excellent UV transmittance, extremely low thermal expansion coefficient and excellent laser damage resistance threshold, making it an ideal choice for harsh applications such as deep UV lithography, fluorescence detection and high-precision laser processing.
In terms of geometric form, this lens belongs to a concave convex lens, consisting of an outwardly convex mirror surface and an inwardly concave mirror surface. Its core optical feature is that the curvature radius of the outer convex surface is smaller than that of the inner concave surface (i.e. the outward curvature is greater than the inward curvature), and this specific crescent shaped design endows the lens with positive focal length characteristics. Compared to traditional biconvex or plano convex lenses, positive meniscus lenses can more effectively correct spherical aberration and coma when used as magnifying or focusing lenses, significantly improving off-axis imaging quality and reducing beam focusing astigmatism. Combined with the advantages of low dispersion and wide spectral transmission of ultraviolet fused silica material, this lens can not only be used as an independent amplification component, but also is often integrated into complex ultraviolet optical systems to optimize the spot shape, improve energy concentration and ensure the high fidelity transmission performance of the system in the ultraviolet wave band.
In response to the diversified application needs of the above high-performance optical elements, the optical probe intelligence provides a standardized series of ultraviolet fused quartz positive crescent lens products, and supports full process customization services. Relying on precision optical processing and detection capabilities, LightSense Intelligence can provide full parameter customization from curvature radius, center thickness, aperture to UV anti reflective film system according to customers' specific technical specifications, ensuring that each lens strictly matches the system design requirements, and providing reliable optical solutions and technical support for scientific research and industrial users.
