LightGateTM 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 (a.k.a. TIR- and RTIR-Prisms). Our bonding technology reduces the air-gap height to 2 μm and provides complete air-gap sealing, resulting in less longterm image degradation by preventing dust or gas from enterning the gap. Precision blackening technology allows accurate positioning and patterning of the absorbtive paint. And envisioning a growing market, all processes have been automated to meet high quality standards at very large production volumes.

Benefits

• Reduced air-gap height for better image contrast
• Sealed air-gap to keep out dust
• Narrow bonding line for large clear aperture
• Precision blackening with patterning capability
• Large glass selection
• Automated manufacturing for reliable high volume production
• Integration of lens or other optical or mechanical parts possible
• Customized design

Applications

• Various projector types using DLP technology
• Pico- and Embedded Projectors
• Business-, Education- and Large Venue Projectors
• LED Projectors
• Laser Projectors
• Hybrid Laser-Phosphor Projectors
• Other DLP based applications
