Flat mirror ZPS Series

copperlaser

In most laser machines, one or several mirrors are used to forward the laser beam from the cavity to the working head. Usually, each mirror deflects the laser beam at an angle of 90°, corresponding to an angle of incidence of 45°. At these mirrors, reflectance should be as high as possible in order to minimize loss of laser power. In addition, phase shift between the s- and p-polarized components of the reflected beam should be as low as possible in order to avoid disturbing the polarization of the laser beam. Mirrors with such properties are called zero-phase mirrors. *Ophir Optics meets ROSH directive according to China ROHS regulation and ROHS2 directive 2011/65/EU Zero Phase Shift High Reflection Mirrors Zero Phase Shift High Reflection Mirrors Ophir Optics new ZPS-HR high reflection coating, demonstrates our innovation and commitment to constantly enhancing our optics performance. The best benefit of the ZPS-HR coating is lower absorption by 40% versus standard ZPS / TRZ coating. Maximum absorption of the ZPS-HR version coating is 0.3%, an improvement to the standard ZPS absorption level of 0.5%. MMR-P MMR-P coating can be used as cavity optics or ZPS (TRZ) and allows for the highest total random polarization reflection available. It can also be applied to a level-changing mirror in two-tiered resonator systems. Our MMR-P coating keeps the same capabilities of phase shift (tolerance of +/- 2 degree) and high reflection of visible light to enable clear observation of HeNe laser or diode laser beam reflection for alignment, location indication, etc. Reflection Spectrum of Typical Bending Mirror Coatings
