Beamsplitters are vital optical components in countless systems—from high-end scientific instruments to everyday imaging devices. Whether you’re designing an interferometer, fluorescence system, or beam combining setup, selecting the right beamsplitter is essential for optimal performance.
This guide summarizes the major form factors and their respective pros and cons.
| Type | Description | Advantages | Limitations |
| Plate Beamsplitters | Flat coated optical substrates | Easy integration, low cost | Beam offset, ghost reflection |
| Cube Beamsplitters | Bonded right-angle prisms | No transmitted beam offset, durable | Higher cost, size restrictions |
| Polarizing Beamsplitters | Dielectric coating on cube or plate | Clean polarization separation | Cube preferred for broadband |
| Non-Polarizing Beamsplitters | Dielectric or hybrid coatings | Maintains polarization | Metallic coatings add absorption |
| Dichroic Mirrors | Thin-film coated plates or cubes | Sharp spectral filtering | Cube design widens transition band |
| Transmission Gratings & Polka Dots | Specialized patterned coatings | Useful for spectroscopy | Less common in standard systems |
Beamsplitters play an important role in many optical systems:
| Application | Beamsplitter Function |
| Interferometry | Splits light to measure interference (e.g., Michelson interferometer) |
| Fluorescence Imaging | Dichroic mirrors separate excitation and emission light |
| Machine Vision | Enables coaxial illumination using plate beamsplitters |
| Sensor Protection | Cold mirrors block thermal IR to protect detectors |
| Lighting Design | Dichroic filters adjust color temperature in illumination systems |
