Large Prisms
Os prismáticos grandes são projetados para um controle de brilho superior e uma distribuição de luz eficiente em ambientes comerciais e industriais. Com geometrias de prisma maiores, essas óticas oferecem um forte controle angular e iluminação uniforme, tornando-as ideais para escritórios de plano aberto, armazéns e espaços de varejo.
- Estrutura Robusta: Adequada para chapas óticas mais espessas e instalações duráveis.
- Forte Controle Angular: Grandes facetas proporcionam uma supressão eficaz do ofuscamento.
- Distribuição Uniforme: Espalhamento de luz em ampla área com luminância consistente.
- Alta Eficiência Ótica: A área de superfície inativa mínima mantém um alto fluxo luminoso (saída de lúmens).

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.
Embalagem
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.
