Dual Wavelength Waveplate, Dual-wavelength Light Source, SHG Lasers
|
Overview:
Dual Wavelength Wave plate is designed to simultaneously meet specific retardation at two individual wavelengths in applications for dual-wavelength light source according to the fitting of the refractive index at different wavelengths. Dual Wavelength Waveplates are particularly useful when used in conjunction with other polarization-sensitive components to separate coaxial laser beams of different wavelengths or elevate and promote the conversion efficiency of Solid State SHG Lasers. Star Optic offers multiple wavelength waveplates majorly Dual Wavelength Waveplates, also including Triple Wavelength Waveplates of high damage threshold.
Main Features of Dual Wavelength Wave Plate:
- Low order or zero order retardation
- High damage threshold
- Various dual-wavelength sets: 780/390nm, 800/400nm, 810/405nm, 1030/515m, 1064/532nm, 1550/775nm
- Support triple wavelength design and production
- Customized retardation length for selection
