Unmounted, Fused Silica, Plano-Concave Lenses, ARB2-VIS
Excelitas offers a comprehensive range of LINOS® unmounted fused silica lenses, available in various focal lengths and diameters, facilitating the selection of optimal components for ultraviolet and high-power optical applications. These lenses are manufactured exclusively from premium materials sourced from reputable suppliers and adhere to stringent tolerances to ensure superior quality. Each standard lens is equipped with double-sided anti-reflection coatings optimized for the visible (VIS) wavelength range to enhance transmittance. Additionally, all lens types are available with a high-quality, black-anodized, engraved aluminum mount.
Plano-concave lenses are supplied unmounted to facilitate flexible and custom integration into optical systems. These lenses provide precise optical performance for applications that require controlled beam divergence. The narrow focal-length tolerances ensure consistent system integration and reliable optical behavior. The ARB2 VIS broadband anti-reflection coating enables high transmission across the 450–700 nm range and offers excellent resistance to laser-induced damage. Fused silica surpasses standard optical glasses in the visible spectrum and delivers superior transmission in the ultraviolet region.
ZEMAX files are provided to streamline optical design and simulation. For customized UV coatings, individual specifications, or higher-volume production, contact us to request a quotation tailored to your specific technical requirements.
