N-BK7 Mounted Plano-Concave lenses, ARB2-VIS
Excelitas offers a wide selection of LINOS® Singlets in multiple focal lengths and diameters for diverse applications. Only premium materials from trusted manufacturers are used, and strict tolerances are maintained to ensure quality. Each standard lens features double-sided anti-reflection coatings optimized for the visible wavelength range to enhance transmittance. Lenses are available mounted in a black-anodized, engraved aluminum housing or unmounted for flexible integration.
Our mounted plano-concave lenses, crafted from high-quality N-BK7, can integrate seamlessly into LINOS Microbench and Nanobench systems. These lenses deliver precise optical performance for applications that require controlled beam divergence. The narrow focal-length tolerances of our plano-concave lenses ensure consistent system integration and reliable optical behavior.
The ARB2 VIS broadband anti-reflection coating delivers high transmission across the 450–700 nm wavelength range while providing excellent laser damage resistance.
ZEMAX files are offered to facilitate efficient optical design and simulation. For custom specifications or higher-volume production, contact us to request a quote tailored to your requirements.
