Mounted UV Fused Silica Symmetric-Concave Lenses, ARHS-YAG
Our LINOS® mounted symmetric concave lenses, made from premium fused silica with a V-coating at 1064 nm, are available in various focal lengths and diameters to meet the needs of demanding YAG laser applications. These lenses are ideal for beam expansion, divergence of collimated light, and applications requiring minimal spherical aberration and balanced optical performance. Each lens is manufactured to tight tolerances for exceptional optical quality and long-term stability. Lenses are offered mounted in a high-quality, black-anodized, engraved aluminum mount or unmounted for flexible integration.
Our mounted symmetric-concave lenses, crafted from high-quality fused silica, 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.
The high-power narrowband anti-reflection coating on a fused silica substrate delivers maximum transmission at the fundamental Nd: YAG wavelength of 1064 nm and offers excellent laser-damage resistance, with a high damage threshold and reliable performance under demanding conditions.
ZEMAX files are available to simplify optical design and simulation. For custom specifications or larger production volumes, contact us for a quotation based on your technical needs.
