Dual Wavelengths Waveplate

Brief Introduction
SinoSi’s Dual wavelength waveplate is a multiple waveplate that provide a specitfic retardance at two different wavelengths, it's particularly useful when used in conjunction with other polarization sensitive components to separate coaxial laser beams of different wavelength.

Low Order Wave Plate

Main Properties

Low Order Waveplates are much better than the multi-order waveplates because of its thinner thickness(less than 0.5mm), better temperature(38°C), wave length(1.5nm) and incidence angle(4.5°) bandwidth and high damage threshold. These properties make it widely used in common applications.

Thickness: 0.2-0.4 mm
High Damage Threshold
Better Temperature Bandwidth
Wide Wavelength Bandwidth
Low Cost
