Beamsplitter Selection Guide

Construction

• 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
