Mounted Fused Silica Plano-Concave Lenses, ARB2-NIR
Excelitas offers a comprehensive selection of near‑infrared (NIR) coated LINOS® fused silica lenses, available across a wide range of focal lengths and diameters to suit demanding high power 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 broadband anti-reflection coatings optimized for the NIR wavelength range, resulting in higher transmittance. In addition to the mounted version with a high quality, black-anodized, engraved aluminum mount, each lens is also available in an unmounted version for convenient custom integration.
Our mounted plano-concave lenses, crafted from high-quality fused silica, integrate seamlessly into LINOS Microbench and Nanobench systems. These lenses deliver precise optical performance for applications requiring controlled beam divergence. The narrow focal-length tolerances of our plano-concave lenses provide consistent system integration and reliable optical behavior.
The ARB2 NIR broadband anti-reflection coating on a fused silica substrate delivers high transmission across the 725–1050 nm wavelength range and offers excellent laser damage resistance, providing 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, please contact us for quotation specific to your technical requirements.
