Types:

• Side-view to top-view conversion
• Dome, flat, or lensed ends
• Rigid or flexible (light guides)

Materials: Clear polycarbonate or acrylic (PMMA).

Key Parameters:

• Transmission efficiency (>90%)
• Viewing angle control
• Color fidelity
• Thermal stability (-40°C to +85°C typical)

Mounting: Snap-in, adhesive, or overmolded.

Design Tips:

1. Match pipe bore to LED size.
2. Minimize air gaps.
3. Avoid sharp bends in flexible types.
4. Use reflective coatings if needed.
