Bote can produce include low-order wave plates, zero-order wave plates, dual-wavelength wave plates and achromatic wave plates.
Low-level wave plates can cause multiple phase delays in the passing beam. It has better mechanical strength and higher laser damage threshold. The delay accuracy is slightly worse than the zero-order wave plate, and the price is lower than the zero-order wave plate. It is a wave coupling plate with good severity.
Low order wave plates produce multiple levels of phase retardation. The thickness is generally around 0.5mm. The wavelength bandwidth is narrow and can only be used for light sources with good monochromaticity.
The temperature stability is not as good as the zero-order wave plate, and the delay accuracy is slightly worse than the zero-order wave plate, but it has better mechanical strength and higher laser damage threshold.
- General thickness 0.2-0.5mm
- High damage threshold
- The price is lower than zero-order wave plate
