Polarizing Cube Beamsplitters

CeNing Optics' non-polarizing beamsplitter cubes use dielectric coating only — no hybrid metallic layer — for negligible energy loss, with P-pol and S-pol transmission precisely controlled near 50% (±2%). N-BK7 substrate, λ/4 surface flatness, and 60-40 surface quality ensure consistent optical performance for narrow-wavelength applications. Read more...

Applying dielectric coating only instead of hybrid metallic coating, the non-polarizing beamsplitter will get no energy loss. The transmittance and reflectance can be precisely controlled to 50%.

Design only by dielectric coating only.
Energy loss negligible
Transmission of P-pol and S-pol are very close to 50% with ±2% Read more...
