Mounted, Uncoated Fused Silica Plano-Concave Lenses

Mounted Plano-Convex Lenses, Fused Silica, ARB2-NIR

Excelitas offers an extensive selection of LINOS^® NIR‑coated fused silica lenses, available in a wide range of focal lengths and diameters, making it easy to identify the ideal components for near‑infrared (NIR) applications. Only premium materials from trusted manufacturers are used in production, with the tightest possible tolerances to guarantee exceptional quality. Each standard lens features double-sided anti-reflection coatings optimized for the near-infrared (NIR) wavelength range to achieve higher transmittance. 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.

Our mounted plano-convex lenses, made from high-quality fused silica, integrate seamlessly with LINOS Microbench and Nanobench systems. Tight focal-length tolerances ensure consistent integration and reliable optical performance. These lenses provide precise beam focusing for demanding applications. The ARB2 NIR broadband anti-reflection coating on fused silica offers high transmission from 725 to 1050 nm and excellent laser damage resistance, ensuring a high damage threshold and dependable performance.

ZEMAX files are provided to streamline optical design and simulation. For customized specifications or higher-volume production, contact us for a quotation tailored to your technical requirements.
