Nd: YAG Harmonic Beamsplitter
Tuniu Optics provides Nd:YAG harmonic beam splitters in standard diameters of 12.7 mm and 25.4 mm. Adopting professional wavelength-selective coating design, these components deliver high-efficiency transmission and reflection for distinct laser spectra to achieve precise beam splitting.
Standard models support common incident angles of 10° and 45°, with customized spectral performance: high reflection at 266 nm and 355 nm, and high transmission at 532 nm and 1064 nm. Custom cube-type splitters and tailored specifications are also available to meet diverse application requirements.
