Ceramic Laser Phosphor Converters

Smart thinking, premium materials and superior design have resulted in Ceramic Laser Phosphor Converters that operate with unrivalled performance.

Stable, tough, efficient and eco-friendly

Color gamut

Yellow and green ceramic phosphor material comprehensively covers the visible color spectrum. For selected applications, white phosphor ceramic is also available.

Reliability and long lifetime

SCHOTT Ceramic Laser Phosphor Converters offer long lifetime and stable operation. Pure inorganic phosphor solutions enable operations at high temperature levels and exhibit exceptional heat conductivity.

High luminance

SCHOTT technology ensures superior illuminance. High efficacy allows high contrast and high light output.

Variable formats

SCHOTT Ceramic Laser Phosphor Converters are available in various formats such as rings, dies, different colors and different heat sink types for dynamic & static solutions.
