Our Deep Prismatic Glass Dome is a specialized optical component designed for easy identification from all angles.
The dual-texture design serves a specific purpose: the concentric rings on the dome’s apex act as a Fresnel lens to concentrate light upwards (ideal for aircraft warning), while the vertical fluting on the cylinder spreads light horizontally. Built to withstand extreme outdoor conditions, this lens is the standard for heavy industrial and transport lighting.
Technical Advantages :
- Dual-Zone Optical Control:
- Zone A (Top): Concentric prismatic rings focus the light source for high-intensity vertical visibility.
- Zone B (Sides): Vertical internal/external ribs diffuse the beam laterally, reducing glare while maintaining signal brightness over long distances.
- Robust Material Options:
- Available in Soda-Lime Glass for standard applications or Borosilicate Glass (Pyrex type) for environments requiring high resistance to thermal shock (rapid temperature changes) and chemical corrosion.
- Weather-Tight Sealing:
- The base features a ground-flat mounting flange (rim). This ensures a perfect compression seal with rubber or silicone gaskets, achieving IP65/IP66 ratings essential for outdoor runway or marine use.
- High-Pressure Molding:
- Pressed glass manufacturing guarantees consistent wall thickness and dimensional accuracy, ensuring every replacement lens fits perfectly into existing metal housings.
