High-performance coating for high-power lasers - optics
Spectral Optics' laser mirrors have a reflectivity of over 99.5% for visible and near-infrared wavelengths. Common laser wavelengths include YAG, helium-neon, argon, and diode lasers as standard. The mirrors are suitable for both beam steering and applications within resonators. For wavelengths shorter than 355nm, Spectral Optics carefully develops coating designs, coating materials, and substrates to provide mirrors with low absorption and high damage thresholds at specific wavelengths. Please consult us regarding the required peak power, pulse width, pulse repetition rate, and expected intensity distribution. The reflectivity of over 99.5% applies to wavelengths of 248nm and longer, while for shorter wavelengths, it is over 97%.
