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. Main Features of Multi Order Waveplate: - Good wavefront distortion and parallelism than combined structure
waveplates
- Withstand high power
- High precision in phase retardation
- Cost efficient and fast delivery
