Why Choose Andover for Fiber Tip Coatings?

Superior Process Control

Our low-temperature coating process is specifically engineered for delicate fiber optics. Using ion-assisted e-beam deposition combined with advanced optical monitoring, we achieve precise coating thickness while preventing thermal damage to fiber components. Our in-house testing shows transmittance stability across -192°C to +500°C operating ranges.

Full Manufacturing Integration

Unlike typical coating houses, we control the entire process in-house. Our clean room facilities, vertically integrated manufacturing, and automated spectrophotometry testing ensure unmatched quality control. When issues arise, we can rapidly adjust processes without relying on external vendors.

Industry-Leading Specifications

  • Laser damage threshold: 85 J/cm² @ 1064nm (10ns pulses)
  • Broad wavelength coverage: 260nm - 2400nm
  • Average reflectance: ≤ 0.5% per surface
  • Environmental testing at cryogenic to elevated temperatures

Expert Support Team

Our engineering team has extensive experience with fiber optic applications. We partner with customers from prototyping through production, offering technical guidance on coating selection and manufacturing processes. With no minimum quantities and typical 2-6 week lead times, we deliver responsive service for both R&D and production needs.
