Custom Chemically Strengthened Etched AG Ultra-Clear Glass Panels
(Chemical Acid-Etched AG | High-Transmittance Low-Iron Base | Safety CNC Finished Edges | Custom Tunable Haze & Ra)
1. Product Overview & Engineering Value
Our Custom Chemically Strengthened Etched AG (Anti-Glare) Glass Panels deliver high-performance optical diffusion and glare suppression for high-end LED lighting luminaires, architectural floodlights, explosion-proof fixtures, industrial display monitors, and optical sensing windows.
Manufactured from Ultra-Clear Float Glass (Low-Iron Glass Substrate), the surface undergoes a controlled chemical acid-etching process. This creates an integral, microscopic anti-glare structure on the glass surface that will never peel, degrade, or scratch off under thermal stress or UV radiation. Combined with ion-exchange chemical strengthening and precision safety edge grinding (2.5D, chamfered, or pencil edge), our panels provide exceptional impact protection, thermal shock durability, and safe assembly handling.
2. Core Technical Advantages & Features
Permanent Chemical Etched AG Surface: Unlike conventional sprayed coatings, chemical acid etching permanently alters the raw glass structure, providing superior resistance to abrasion, scratches, weathering, and harsh chemical cleaning agents.
Ultra-Clear Low-Iron Base Substrate: Eliminates the natural greenish edge tint of standard glass, ensuring true color rendering, superior beam uniformity, and maximum luminous efficacy for LED lights.
Fully Tunable Optical Parameters: Haze (3%–50%), surface roughness (Ra 0.05–0.50 um), and optical transmittance (88%–91%+, or up to 98% with AR coating) can be custom-formulated to balance anti-glare effects with light output.
Ion-Exchange Chemical Strengthening: Surface compressive stress (CS >= 450–650 MPa) significantly boosts flexural strength and mechanical shock resistance (IK07–IK09 rated), preventing cracking caused by rapid thermal cycles.
Safety Edge Processing: CNC ground safety edges (flat polished edge, 2.5D C-edge, R-edge, or arris edge) remove sharp burrs to protect operators during assembly.
Turnkey Custom Fabrication: Thickness, custom outer dimensions, CNC step-milled borders, waterjet through-holes, and high-temperature silk-screened borders are fully customizable according to your CAD drawings.

6. Frequently Asked Questions (FAQ)
Q1: What is the main advantage of Chemical Acid-Etched AG over Sprayed AG coating for LED fixtures?
A: Sprayed AG is an applied polymer/silica coating that easily degrades, scratches, and discolors under continuous heat from high-power LEDs or outdoor UV exposure. Chemical acid etching directly textures the surface of the raw glass, making the anti-glare and light-softening properties permanent, heat-resistant, and scratch-proof.
Q2: How do Haze and Surface Roughness (Ra) impact LED light diffusion?
A:
Low Haze / Low Ra (Haze 3%–12%, Ra < 0.1 um): Disperses ambient glare while maintaining high light transmission and optical sharpness for display monitors.
Medium-to-High Haze / Higher Ra (Haze 15%–45%, Ra 0.15–0.45 um): Blends LED point light sources into a uniform, soft beam, effectively eliminating harsh hot-spots and dazzle.
Q3: What safety edge finishing options do you provide?
A: We offer safety arrissed edges (45° micro-chamfer), flat CNC polished edges, 2.5D beveled edges, and round (pencil) edges. All sharp corners and micro-cracks are eliminated to ensure safe handling during luminaire assembly.
Q4: Can you produce custom shapes, holes, and silk-screen printed borders?
A: Yes. We manufacture directly from your 2D/3D CAD drawings (DXF, DWG, STEP, PDF). We provide CNC hole cutouts for mounting screws or sensors, stepped (rabbeted) borders for waterproof gasket seating, and high-temperature black/white ceramic silk screen printing.
Q5: What is your standard lead time for custom samples and mass production?
A: Custom prototypes and optical evaluation samples typically take 7 to 10 working days. Mass production takes 12 to 18 working days depending on batch size and processing complexity.
