Low volume-scattering ceramics for optical measurement / inspection applications
Low Volume-scattering Technical Ceramics
LovTEC
Features
- ・Low volume scattering inside the ceramics resulting in low optical penetration
- ・Most incoming light is reflected diffusely, even as a mirror there is low regular reflection
- ・High total reflectivity: Pure white, 90% or more of visible spectrum
- ・Low thermal expansion: 0.6 x 10-6/K at room temperature (super invar alloy equivalent)
- ・Supports ultra-precise machining (sub-micron order flatness/sphericity)
- ・No rust
- ・Light weight (Bulk density 3.0 g/cm3)
