Laser Polarized Dichroic Mirror

Laser Polarized Dichroic Mirror for Projection Display

Materion Balzers Optics’ laser polarized dichroic mirror have superior performance. The polarization of light affects the focus of laser beams, and can be important to prevent unwanted back reflections. Materion Balzers Optics’ laser polarized dichroic mirrors have high transmission in P- polarized light and high reflection in S-polarized light, or have high transmission in S-polarized light and high reflection in P-polarized light which help customer to maximize the total light throughput. The coating design have been specific optimization for P and S polarized light emitted by different lasers, and can be applied to RGB pure laser systems, laser phosphor illumination systems or polarization light source systems.

Benefits

• High reflection and high transmission in the Red, Green,Blue laser respective wavelength ranges.
• Narrow cut-on/cut-off spectral tolerances and excellent spectral uniformity.
• Excellent optical and mechanical stability contributed by the plasma sputtering deposition process (20 –120° temperature shift < 1nm, 48 h humidity shift < 1nm).
• High degree of flexibility for customization spectrum design

Applications

• RGB pure laser system
• Laser phosphor illumination system
• Polarized light source system
• LCOS projection system
• Laser interferometer
