Ø25.4mm Zero-Order Waveplates

產品名稱 : Ø25.4mm Zero-Order Waveplates
產品說明 :
Waveplates are made from materials that exhibit birefringence. The velocities of extraordinary and ordinary rays through birefringent material varies inversely with their refractive indices. This difference in velocities gives rise to a phase difference when the two beams recombine. At any specific wavelength, the phase difference is governed by the thickness of the retarder (waveplate).

Standard waveplates are based on air-spaced construction that allows their use for high-power applications. The damage threshold is more than 20 J/cm² for 10 ns pulses @ 1064 nm.

Our waveplates are made from excellent-quality laser-grade crystalline quartz material.
Best suited to narrow bandwidth and operating temperature range.
