25.40mm Laser Mirrors


Our Laser Mirrors offer high performance at an affordable price. Details of our laser mirrors include:

  • High Damage Thresholds: Each batch of mirrors is checked by a third party test facility for compliance.
  • High Reflectivity: Each batch of mirrors is scanned for absolute reflection on one of our state-of-the-art, calibration maintained spectrophotometers.
  • Clean Packaging: To minimize contamination, the mirrors are packaged in PETG containers in class 100 HEPA filtered flow benches.
  • High Quality Substrate: Only high quality materials, such as UV Grade Fused Silica, are used.
