Achromatic Waveplate WPH412
Description
Achromatic waveplate is similar to Zero-order waveplate except that the two plates are made from different materials, such as crystal quartz and magnesium fluoride. Since the dispersion of the birefringence can be different for the two materials, it is possible to specify the retardation values at a wavelength range. Hence, the retardation of the resulting waveplate can be made to low sensitivity to wavelength change. Based on the contact methods of two plates, we classify the achromatic waveplate to two types: Airspaced and Cemented.

Frequently Asked Questions
An achromatic waveplate is similar to a zero-order waveplate but made from different materials to reduce sensitivity to wavelength change.
The two plates of an achromatic waveplate are made from different materials, while a zero-order waveplate is made from a single material.
The two types of achromatic waveplates are airspaced and cemented, based on the contact methods of the two plates.
The wavelength range for the achromatic waveplate is VIS:465-650nm; NIR:700-1000nm; IR:1200-1650.
The diameter of the quarter waveplate is 12.7mm with a tolerance of +0.0; -0.1 mm.
