Advanced Heat Absorbing Glass for Optical Protection
Our heat absorbing glass (also known as heat insulating filters) is specifically engineered to absorb near-infrared radiation and reduce thermal stress on sensitive optical components. It maintains high visible light transmission while effectively blocking heat, making it ideal for high-intensity illumination systems.
Technical Specifications & Equivalents
We provide various grades of heat-absorbing material, equivalent to international standards for versatile applications:
| Feature | Description |
|---|---|
| Material Grades | Equivalent to KG1, KG2, KG3, KG5 |
| Visible Transmission | > 80% (depending on thickness) |
| IR Absorption | Effective blocking from 750nm to 2500nm |
| Thermal Stability | Up to 200°C – 300°C (Tempered options available) |
Why Use Our Heat Insulating Filters?
- System Longevity: Prevents overheating of sensors and film gates.
- High-Intensity Support: Used in cinema projectors, medical lighting, and stage lights.
- Custom Fabrication: Round, square, and complex CNC shapes up to 300mm.
- Surface Precision: Scratch-Dig 60/40 standard, 40/20 available for precision optics.
