Zero Order Dual Wavelength Waveplate
Zero Order Dual Wavelength Waveplate can provide the retardance at two wavelengths (the fundamental wavelength and the second harmonic wavelength) at the same time, and is widely used in femtosecond lasers.
- Mounted in Ø25.4 x 6 mm Black Anodized Ring Mount
- High Damage Threshold
- Better Temperature Bandwidth
- Wide Wavelength Bandwidth
- Ultra-thin thickness, low material dispersion
