Multiple Order λ/4 Quarter Wave Plate, High Damage Threshold, Low Cost

Overview:

A Multiple Order Wave plate is made from a single birefrigent crystal (crystal quartz is the most commonly used material) that produces an integer multiple of the rated retardance. Quarter Wave Plate is one of the common types of waveplates which converts linearly polarized light into circularly polarized light or vice versa.

While a multiple order waveplate produces an integer multiple of rated retardance, by contrast, a zero order waveplate produces exactly the speficied retardance. Multiple order waveplates has limit to working bandwidth and the retardance is more sensitive to temperature, however, for many applications where increased sensitivities are not a concern, they are widely used due to its undeniable economical advantage.
