Features


  • High-Quality Reflective Surface: Our mirrors feature a highly polished surface with a thin coating of aluminum or silver, ensuring optimal light reflection.

  • First Surface Mirrors: Designed for optical applications, these mirrors have the reflective coating on the front surface to eliminate the optical properties of the glass from affecting light.

  • Protected Aluminum Coating: All mirrors come with a protected aluminum coating applied to the front surface for enhanced durability and performance.

  • Material Options: Available in BK7 Grade A optical glass and UV Grade Fused Silica for different application needs.

  • Dimensional Precision: Both standard and high-grade mirrors offer a dimensional tolerance of +0.0/-0.1mm, ensuring precise fit and function.

  • Surface Flatness: Standard grade mirrors have a flatness of λ/5 @ 632.8nm, while high-grade mirrors offer superior flatness at λ/10 @ 632.8nm.

  • Surface Quality: The mirrors feature excellent surface quality with scratch/dig specifications of 40/20 for standard grade and 10/5 for high-grade mirrors.

  • Thickness Tolerance: All mirrors maintain a thickness tolerance of ±0.2mm for consistent performance.

  • Parallelism: Ensures high precision with parallelism of less than 3 arc minutes.

  • Custom Options Available: We offer custom versions of all products. Send us your drawings or specifications for a personalized quotation.
