Metallic coated beam splitters offer superior broadband and stable optical performance compared to dichroic types. Their metallic coatings provide effective reflection and transmission across a wide spectral range—from ultraviolet to infrared—ensuring consistent results for broadband applications. Unlike dichroic coatings, metallic coatings are largely insensitive to incident angle and polarization, maintaining a stable and uniform 50:50 split ratio even under varying conditions.
They deliver non-dispersive performance without color separation, making them ideal for imaging, metrology, and laser alignment systems. Additionally, metallic beam splitters feature durable protective overcoats that ensure excellent resistance to humidity, temperature fluctuations, and long-term environmental exposure, providing reliable and maintenance-free operation over time.
