Description

Multiple Order λ/2 Half Wave Plate, High Damage Threshold, Low Cost

Overview:

Multiple Order Wave plate means the fact that the retardance of a light path will undergo a certain number of full wavelength shifts in addition to the fractional design retardance. Half Wave Plates are typically used to rotate the polarization of light.

The net effect of multi order waveplate at the design wavelength is basically the same as zero order waveplate. But the optical bandwidth is limited. Also, the retardance has a higher temperature sensitivity. However, compared to zero order waveplates, multi-order wave plates are a more economical solution for many applications where increased sensitivities are not an issue.

Main Features of Multi Order Wave Plate:

Good wavefront distortion and parallelism
High damage threshod
High precise phase retardation
Large size available and fast delivery
Economical solution
