Polarizing Beamsplitter Cubes
- Optical bonding for epoxy-free optical paths
- High-energy laser-line and broadband designs
- Convenient 90° beam separation
- Custom cubes for multiple wavelengths or wavelength regions available
- RoHs Compliant
PPC beamsplitter cubes are derived from a unique combination of IBS coatings, ultraprecise fabrication capabilities and our patent-pending, epoxy-free bonding technology—Chemically Activated Direct Bonding™ (CADB®) which results in a zero-bondline thickness. In addition to the standard sizes and wavelengths shown, we can produce high-energy cube beamsplitters from 1×1 mm2 in size, and in a wide variety of materials including fused silica, BK7, YAG, and other optical glasses and crystals.
Whether you need 10 or 10,000 pieces, our precision wafer-based processes result in high yields and competitive costs, especially at higher volumes. These high-precision assemblies have been widely used in telecommunications, semi-conductor and biomedical applications where transmission efficiency, extinction ratio and wavefront quality are all critical specifications.
Call us for more information on high-energy narrowband and broadband polarizing beamsplitter cubes for other wavelengths from 266 nm to 3000 nm, or to discuss your requirements for custom waveplates, polarizers and micro-optic assemblies.
