Cell Lab 4N (99.99%) Sodium Fluoride (NaF) Sputtering Target

High-Purity NaF Target for Optical Coatings and Electronic Applications

General Description

Cell Lab 4N (99.99%) Sodium Fluoride (NaF) Sputtering Target is a high-purity ceramic material widely used for optical coatings, dielectric layers, and thin-film deposition. Known for its high transparency, low refractive index, and strong chemical stability, NaF is frequently applied in anti-reflective coatings, UV optics, and laser components. Its excellent thermal resistance and insulation properties also make it suitable for semiconductor and protective layer fabrication.

Key Features

  • High Purity (99.99%) – Ensures minimal contamination and consistent film performance.

  • Excellent Optical Transmission – Ideal for UV and visible optical coatings.

  • Stable and Chemically Inert – Resistant to moisture and most reactive gases.

  • Versatile Form Factors – Available in disc, rectangular, and custom shapes.

  • Customisable Dimensions – Sizes, thickness, and bonding options available upon request.

FAQ

Q1: Is NaF compatible with high-temperature sputtering systems?
Yes, Sodium Fluoride can be sputtered at moderate temperatures; however, precise control of the chamber environment is required to prevent moisture absorption.

Q2: What is the typical purity level for optical-grade NaF targets?
Cell Lab provides NaF targets with 99.99% purity, suitable for optical and dielectric thin-film applications.

Q3: Can custom sizes and thicknesses be manufactured?
Absolutely. We can produce custom geometries and bonded configurations for specific coating systems.

Q4: Does the target come pre-bonded to a backing plate?
No, the standard product is supplied without one, but copper backing plates with indium bonding are available as an optional add-on.
