Hexagon
The Hexagon series features a symmetrical hexagonal microprismatic structure engineered for multi-directional glare control and uniform luminance. Its refined prism geometry delivers smooth light distribution with reduced sparkle, making it ideal for premium architectural and commercial luminaires.
- Clean Visual Appearance: Smooth surface with reduced sparkle.
- Stable Thin-Sheet Structure: Strong geometry for thin films and sheets.
- Multi-axis Glare Control: Balanced cutoff in all directions.
- High Optical Efficiency: Minimal dead zones for maximum output.
- UGR < 19 Compliant: Designed for glare-sensitive environments.

Photometric Data
Optical Performance & Refraction
Geometric Activation
Notice how the hexagonal prisms ‘engage’ upon illumination. Each convex cell captures raw, uncontrolled LED output and redirects it into the useful task plane, physically suppressing high-angle glare to achieve UGR <19 compliance.
The UGR<19 optical stack delivers a consistent diffusion across the panel:
- Microprismatic sheet +
- Diffuser film/sheet
Applications

Product Tolerances
The three materials (PMMA, PC and PS) have similar tolerances.
| Property | Value |
| Thickness | ±3% |
| Mother board Length / Width | ±3.0 mm |
| Cut-to-Size Length / Width | ±0.3 mm |
| Light Transmittance & Haze | ±2% |
Note: PMMA has the highest thermal expansion coefficient among diffuser materials. This means it can expand in hot conditions and contract in cold conditions. Use our Thermal Expansion Calculator to predict the final dimensions before installation.
Packing
At Hexatron Technologies, we take great care in packing our diffuser sheets to ensure they reach our customers in perfect condition.
1. Standard Sheet Packing
- Mother Sheets: Large sheets (up to standard extrusion sizes) are stacked on pallets or crates.
- Final Cut / Cut-to-Size Sheets: Smaller sheets are carefully wrapped and separated with protective films or kraft paper, then bundled to avoid bending or warping.
2. Protection Methods
- Surface Protection Film: All diffuser sheets are supplied with a removable protective film to prevent scratches and contamination.
- Edge Guards / Corner Protectors: To prevent chipping or denting during handling and shipping.
3. Palletization & Securing
- Sheets are stacked on pallets or crates with interleaving layers and secured with straps or stretch film to prevent movement during transit.
- Maximum stack height is calculated based on sheet thickness and material to avoid warping or deformation. A pallet of 1.5 tons is the maximum weight.
4. Shipping & Handling Recommendations
- Flat Storage: Sheets should be stored flat and supported evenly to maintain flatness.
- Climate Considerations: Avoid prolonged exposure to extreme temperatures or humidity, especially for PMMA, to prevent dimensional changes.
- Handling: Use gloves when removing protective film to prevent fingerprints.
