Beamsplitter Selection Guide
Construction
Cube Beamsplitters- Made from two triangular glass prisms
- Cemented at base using epoxy or urethane adhesives
- Low wavefront distortion and precise parallelism
- Ideal for high-precision applications
- Thin optical glass with coatings
- Lower chromatic aberration
- More cost-effective than cubes
- No optical cement required
- More compact design
Functional
Non-Polarizing Beamsplitters
- Maintains original polarization state
- Split ratios could be range from 50:50 / 30:70 / 90:10
- Higher damage threshold
- Better thermal stability
Polarizing Beamsplitters
- Splits light into S and P polarization
- Designed for specific laser wavelengths
- Suitable for high-power laser applications
- Used in optical isolation
Dichroic Beamsplitters (Or Dichoric Mirror)
- Separates light by wavelength
- Used for laser beam combining
- Common in fluorescence applications
- Available as long-wave pass or short-wave pass
