The PP-UVFS-12.7-6.35-PR216-AR419 is a precision 1064 nm partial reflector / output coupler designed for Nd laser resonators and other optical systems that require a controlled reflectance-to-transmittance ratio at 1064 nm. Manufactured on a 12.7 mm UV fused silica substrate with 6.35 mm thickness, this optic features an IBS dielectric coating engineered for 50% ±2% reflectivity on the front surface at 1064 nm and a low-reflection AR coating on the rear surface to minimize parasitic losses and help maintain cavity efficiency.

This output coupler is intended for use at 0° angle of incidence and is well suited for laser cavity architectures where stable partial reflection is needed to extract a defined portion of intracavity power while returning the remaining light back into the resonator. The use of UV fused silica provides excellent optical homogeneity, low absorption, and good thermal stability, while the ion-beam sputtered coating design supports high durability, low scatter, and consistent spectral performance in demanding laser environments.

With its combination of 50% reflectivity at 1064 nm, AR-coated second surface, and precision optical specifications including surface flatness better than λ/8 at 633 nm, the PP-UVFS-12.7-6.35-PR216-AR419 is a strong choice for OEM laser integration, laboratory resonator development, and industrial Nd systems that require a reliable 1064 nm output coupler mirror.
