Price of Single-Mode Fiber Optic Coated Mirror

Single-mode fiber optic coated mirrors typically range from several hundred to over a thousand USD per unit, depending on coating type, reflectivity, and customization. OverviewSingle-mode fiber optic mirrors, including Faraday rotator mirrors (FRMs) and high-reflectivity fiber cavity mirrors, are precision optical components used in quantum optics, fiber networks, and high-stability measurement systems. These mirrors are fabricated directly on fiber end facets and can feature dielectric coatings, broadband or high-finesse stacks, and custom radii of curvature.

They are available in stock configurations for common wavelengths or fully customized for specific experimental requirements.

Factors Affecting Price

Coating Type: Dielectric coatings with high reflectivity or multiple stop bands are more expensive than uncoated or standard coatings. Mirror Geometry: Concave or custom-shaped mirrors with precise radii of curvature require advanced laser machining, increasing cost. Fiber Type: Single-mode fibers are generally more costly than multi-mode fibers due to tighter tolerances and alignment requirements.

Additional Features: Options like tapered tips, connectors, planar mirror pairs, or Faraday rotation functionality can add to the price. Quantity and Lead Time: Stock items are usually less expensive than fully custom mirrors, and bulk orders may reduce per-unit cost.

Typical Price Range

Stock single-mode fiber mirrors: Approximately $300–$800 USD per unit for standard coatings and common wavelengths. Custom high-reflectivity or Faraday rotator mirrors: Prices can exceed $1,000 USD per unit depending on specifications, coating complexity, and precision requirements.

Purchasing Recommendations

Contact suppliers like Qlibri, FiberCavities.com, or Kerns Tech for quotes based on your exact specifications. Specify wavelength, reflectivity, curvature, fiber type, and any additional features to receive an accurate price. Consider stock mirrors for rapid deployment if your wavelength and specifications match standard offerings.

By providing detailed specifications to the manufacturer, you can obtain a precise quote and ensure the mirror meets your experimental or network requirements.
