Unmounted Symmetric-Convex Lenses

Unmounted Symmetric-convex lenses, ARB2-NIR

Excelitas offers an extensive selection of LINOS® symmetric-convex lenses optimized for the near infrared (NIR) wavelength range. These lenses are available in various focal lengths and diameters to meet the specific needs of diverse optical applications. Only premium materials from trusted manufacturers are used in production, with the tightest possible tolerances to ensure exceptional quality. Standard lenses feature double‑sided NIR anti‑reflection coatings to enhance transmittance and minimize surface reflections. In addition to the unmounted versions, each lens type is offered with a high-quality, black-anodized, engraved aluminum mount.

Precision-designed for 1:1 imaging, these lenses feature two equal radii of curvature, ensuring precise, consistent optical performance in applications that require exact image replication. Our symmetric-convex lenses are made from high-quality N-BK7 glass and supplied unmounted for flexible integration into custom optical systems. Their narrow focal-length tolerances ensure consistent integration and reliable optical performance.

The ARB2 NIR broadband anti-reflection coating on fused silica provides high transmission from 725 to 1050 nm and offers excellent laser damage resistance for reliable performance in demanding environments.

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.
