Dual Wavelength Anti-Reflective Coatings(Part No: DAR)

Dual wavelength antireflective coating is designed to provide very high transmission at two different wavelength. This coating is often used in frequency doubling systems or the other multi-laser output systems. Such as the Nd:YVO4 laser (1064nm) and its second harmonic generation(532nm) green laser.
