Achromatic Waveplate is similar to zero order waveplate except that the two plates are made from different birefringent crystals. Since the dispersion of the birefringence of two materials is different, it is possible to specify the retardation values at a broad wavelength range. So, the retardation will be less sensitive to wavelength change. In other words, it can be used at a broadband wavelength range.

Technical Advantages of Achromatic Waveplate:
Through innovative material and structural designs, the achromatic waveplate overcomes the limitations of traditional waveplates. Utilizing technologies such as quartz/magnesium fluoride (MgF₂) dual-material cascading, it achieves a phase retardation error of <5% across a broad spectral range of 400–2000 nm. It also exhibits stable performance under large angles of incidence (±45°) and wide temperature ranges (-40°C to 85°C). In fields such as laser processing, fiber optics communication, scientific research, and imaging systems, this component enables precise control of polarization states across multiple wavelengths, reduces bit error rates, enhances measurement accuracy, and drives the development of optical systems toward higher precision and integration.
