LightGate™ for DLP Projection

Setting higher standards for TIR and RTIR Prism Assemblies

New competence has enabled Materion Balzers Optics to improve the standards in LightGateTM manufacturing (aka TIR and RTIR prisms). Our bonding technology reduces the air-gap height to 2 μm and provides complete air-gap sealing, resulting in less long-term image degradation by preventing dust or gas from entering the gap. Precision blackening technology allows accurate positioning and patterning of the absorptive paint. Envisioning a growing market, all processes have been automated to meet high quality standards at very large production volumes.
