Custom AR Coating Glass Panels & High-Transmission Substrates

1. Product Overview & Optical Highlights

Chenshi Tech specializes in engineering and thin-film deposition of custom AR coating glass (anti-reflective coating glass) panels. Utilizing magnetron sputtering and electron-beam physical vapor deposition, our optical dielectric coatings minimize surface reflection and dramatically enhance light throughput across visible and near-infrared spectrums.

Depending on application requirements, we provide single-sided AR coating achieving visible light transmittance (VLT) exceeding 94.5%, and double-sided AR coating glass reaching over 98.5% transmittance. While raw quartz and borosilicate substrates inherently deliver around 92% transmission, applying our optical AR thin films eliminates surface glare and ensures maximum optical efficiency.

Complementing our custom borosilicate 3.3 glass panels and high-precision optical quartz glass plates, our custom AR coating glass provides high-efficiency anti-glare clarity for electronic displays, facial recognition scanners, automotive consoles, and optical equipment viewports.

3. Engineering Advantages of AR Coating Glass

1. Unmatched Optical Transmittance: By depositing alternating layers of high and low refractive index dielectric materials, our AR coating glass destroys destructive surface reflections. Double-sided coating boosts visible light throughput from 92% to over 98.5%, delivering bright image projection and vivid display readability.

2. Broad Material Compatibility: We coat a diverse spectrum of substrates. From thermally resilient borosilicate 3.3 glass and ultra-pure UV fused silica quartz to ultra-thin flexible float glass, the coating exhibits robust mechanical adhesion and thermal endurance.

3. Glare Elimination and Visual Comfort: In outdoor sunlight and high-ambient lighting environments, untreated glass causes harsh specular reflections that obscure screens and sensors. Our AR treatment cuts surface reflectance to under 0.5%, ensuring rapid optical scanning and eye fatigue relief.

4. Core Applications & Industry Use Cases

• Display Protection Screens: High-end screen protective glass, ruggedized outdoor monitors, and commercial interactive touch kiosks.

• Touch Display Panels: Industrial HMI operator terminals, banking ATM interfaces, and smart home appliance touch consoles.

• Electrical & Switch Panels: Luxury smart touch wall switches, architectural control faceplates, and digital indicator panels.

• Facial Recognition & Biometric Scanners: Security turnstiles, optical fingerprint readers, biometric facial recognition cameras, and access control terminals.

• Automotive Center Consoles: In-vehicle navigation displays, digital instrument clusters, head-up display (HUD) combiner glass, and electronic rearview mirror covers.

• Optical Equipment Viewing Windows: Industrial process inspection viewports, laser protection windows, camera sensor filter plates, and laboratory spectrometer viewports.

5. Frequently Asked Questions (FAQ)

Q: What is the primary difference in performance between single-sided and double-sided AR coating?

A: Single-sided AR coating reduces reflection on one glass surface, boosting overall visible transmittance to over 94.5%. Double-sided AR coating eliminates reflection on both internal and external surfaces, maximizing total light transmission to greater than 98.5%. Double-sided coating is recommended for high-precision sensor viewports and outdoor optical displays.

Q: How does base substrate selection affect the final transmittance of AR coating glass?

A: High-purity base substrates such as optical quartz glass and borosilicate 3.3 glass have lower internal bulk absorption and an uncoated transmittance around 92%. When coated with broadband AR thin films, they achieve peak transmission up to 99% across wide spectral bands.

Q: What thicknesses can you fabricate for custom AR coating glass?

A: We provide standard in-stock thicknesses between 1.1 mm and 3.0 mm for immediate CNC sizing, and fully support custom processing across the complete range of 0.1 mm ultra-thin cover plates up to 10.0 mm heavy-duty viewing windows.

Q: Can AR coating be combined with Anti-Fingerprint (AF) oleophobic treatments?

A: Yes. We frequently manufacture dual-treatment “AR + AF” panels. The AR layer delivers maximum optical clarity (>98%), while the hydrophobic AF topcoat provides an easy-to-clean water contact angle over 115 degrees, repelling oils, fingerprints, and smudges.
