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
