- This material, known as Spinel, is made from a synthetic powdered clay that is heated and pressed under vacuum (aka sintered) into transparent sheets.
- Unlike most forms of commercially available bulletproof glass, Spinel doesn’t block the infrared wavelength of light. That means that this stuff can protect a UAV’s surveillance camera or the lens of a HEL-MD laser without hindering the device’s operation.
- Plus, Spinel weighs just a fraction of a modern bulletproof pane and reduces the weight by a factor of two or more.
