The true zero-order waveplate means that the thickness of waveplate is very thin(less than 0.1mm)which make the true zero-order waveplate excellent in temperature, wavelength and incident angle (about 20 ) bandwidth. Therefore, it is excellent choice for the highly accurate application. It is cemented with a block of glass which is limited to low and medium power application

| Material: | Crystal Quartz |
| Dimension Tolerance: | +0.0, -0.2 mm |
| Retardation: | l/8, l/4, l/2, or l(typical) |
| Retardation Tolerance: | up to l/500 |
| Thickness: | 0.2~0.5mm (determined by retardation) |
| Wavelength Range: | 400-2100 nm |
| Parallelism: | <1 arc second |
| Surface Quality: | 20-10 scratch and dig |
In order to enable the waveplate suitible for high damage threshold (more than1GW/cm2)
application: We provides a single plate of true zero-order waveplate. The thickness of this waveplate means handling can be difficult, we can provide mounts upon request.
