Product Family Description

  • 532 and 1064nm Dual-Band Anti-Reflection Coating
  • 10-5 Surface Quality and λ/10 Surface Flatness
  • Ideal for Nd:YAG Laser Systems
  • Uncoated Laser Window Substrates Available

TECHSPEC® Dual-Band Anti-Reflection (AR) Laser Windows provide high performance AR coatings designed to be used in multi-wavelength laser applications. The anti-reflection coatings on both surfaces feature <0.25% reflection at 532nm and <0.1% reflection at 1064nm, significantly increasing laser throughput. These laser windows feature excellent thermal stability, precision grade λ/10 surface flatness, and 10-5 surface quality, ensuring minimal distortion to transmitted beams. TECHSPEC® Dual-Band Anti-Reflection (AR) Laser Windows are available in standard imperial sizes for convenient integration into existing laser systems and are ideal for Nd:YAG applications including those used in aesthetic laser systems. Contact us if your application requires a custom coating or design.

Note: Damage thresholds values are tested independently.
