Mounted, Uncoated Fused Silica Plano-Concave Lenses

Mounted UV Fused Silica Symmetric-Convex Lenses, ARB2-VIS

Excelitas offers an extensive selection of LINOS^® fused silica lenses optimized for the visible (VIS) wavelength range. Available in a wide variety of focal lengths and diameters, these lenses are designed to help you identify the ideal components for high‑power optical applications. Only premium materials from trusted manufacturers are used, with the tightest possible tolerances to guarantee exceptional quality. Standard lenses feature double‑sided VIS anti‑reflection coatings that enhance transmittance and reduce surface reflections. In addition to the mounted version with a high-quality, black-anodized, engraved aluminum mount, each lens is also available unmounted for convenient custom integration.

Precision-engineered for 1:1 imaging, these lenses feature two equal radii of curvature, delivering accurate and reliable optical performance for applications that demand exact image replication. The ARB2 VIS broadband anti-reflection coating ensures high transmission across the 450–700 nm range and excellent laser damage resistance. Fused silica outperforms standard optical glasses in the visible spectrum and provides superior transmission in the UV.
