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%
