High-Performance Materials for Optical Coatings

Optical coatings are integral to a wide array of industries, from consumer eyewear to advanced laser systems, aerospace, defence and automotive technology. At Testbourne, we provide a comprehensive range of high-purity materials and equipment for producing precision thin-film optical coatings via PVD (Physical Vapour Deposition).

Wide-Ranging Applications

Our materials are used in the fabrication of:

• Anti-reflective (AR) coatings for glasses, lenses and camera systems
• IR coatings for thermal imaging and night vision
• Beamsplitters for laser optics and sensors
• Multilayer interference coatings for high-performance optical filters
• Protective and scratch-resistant coatings for displays and windows

These coatings are critical for enhancing light transmission, reducing glare, protecting surfaces, and controlling spectral performance in both consumer and industrial optical systems.

Materials & Equipment for PVD Optical Coatings

We supply:

• Evaporation Materials: Oxides, fluorides, and metals used in optical layer deposition
• Electron Beam Crucibles: High-precision evaporation tools for uniform coatings
• Evaporation Boats & Filaments: Ideal for thermal evaporation processes
• Quartz Crystal Sensors: For in-situ thin-film thickness monitoring
• Thin-Film Deposition Equipment: Supporting R&D and production-scale coating applications

All our materials are selected for their optical clarity, purity and repeatable deposition behaviour, crucial for the demanding specifications of modern optical devices.

Frequently Asked Questions about Optics

What are the most common materials used for optical coatings?

We offer high-purity metal oxides (e.g., TiO₂, SiO₂, Al₂O₃) and fluorides (e.g., MgF₂, CaF₂), ideal for anti-reflective, IR, and dielectric coatings.

Can your materials be used for laser optics and filters?

Yes. Our evaporation materials and crucibles are frequently used in precision laser optics, notch filters, and optical bandpass filters for industrial and medical lasers.

Do you supply materials for IR and UV coatings?

Absolutely. Our range includes materials suitable for infrared (IR) and ultraviolet (UV) spectrum coatings, offering high transmission and thermal stability.

What deposition methods are supported?

Our materials are compatible with thermal evaporation, electron beam evaporation, and ion-assisted PVD techniques, widely used in thin-film optical manufacturing.

Do you offer technical support or coating recommendations?

Yes. We work closely with clients to recommend optimal coating materials, stack designs, and deposition systems for specific optical performance goals.
