Partial Reflectors » Nd:YAG Harmonic Separators

Harmonic Separators are designed to efficiently separate Nd:YAG harmonics.

The substrate is coated on one side with an RMAX/TMAX coating that is optimized for maximum reflection of one harmonic frequency and maximum transmission of another. The reverse side is coated with a high efficiency, narrowband, anti-reflection coating.
