Symmetric-Concave Singlet Lenses

Mounted N-BK7 Symmetric-Concave Lenses, ARHS-YAG

LINOS® mounted symmetric-concave lenses are available in a comprehensive selection of focal lengths and diameters, manufactured from high-quality N-BK7 optical glass and optimized with a V-coating for 1064 nm applications. Designed to deliver reliable performance across a wide range of optical systems, these lenses are ideally suited for beam expansion, controlled divergence of collimated light, and applications requiring low spherical aberration with well-balanced imaging characteristics.

Precision manufactured to tight tolerances using premium optical glass sourced from trusted suppliers, each lens provides outstanding optical quality, consistency, and long-term reliability. Our mounted versions feature a high-quality, black-anodized, engraved aluminum mount, while unmounted versions are also available for added flexibility and convenience in custom optical designs and OEM integration.

Our mounted symmetric-concave lenses are crafted from high-quality N-BK7 glass and integrate seamlessly into LINOS Microbench and Nanobench systems. Their narrow focal-length tolerances ensure consistent system integration and reliable optical behavior.

These lenses feature two equal radii of curvature, providing precise optical performance for applications requiring controlled beam divergence.

They feature high-power narrowband anti-reflection coating to ensure maximum transmission at the fundamental Nd:YAG wavelength of 1064 nm and excellent laser damage resistance, delivering a high damage threshold and reliable performance under demanding conditions.

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.
