Large Prisms
Les optiques prismatiques de grande taille sont conçues pour un contrôle supérieur de l’éblouissement et une distribution efficace de la lumière dans les environnements commerciaux et industriels. Grâce à des géométries de prismes élargies, ces optiques offrent un contrôle angulaire précis et une illumination uniforme, ce qui les rend idéales pour les bureaux en open-space, les entrepôts et les espaces de vente.
- Structure Robuste : Adaptée aux plaques optiques plus épaisses et aux installations durables.
- Contrôle Angulaire Précis : Les grandes facettes permettent une suppression efficace de l’éblouissement.
- Distribution Uniforme : Diffusion de la lumière sur une large zone avec une luminance constante.
- Haute Efficacité Optique : La surface inactive minimale permet de maintenir un flux lumineux élevé (rendement en lumens).

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.
Emballage
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.
