Achromatic Waveplate WPH415
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
The difference is in the contact methods of the two plates. Airspaced achromatic waveplates have a small air gap between the two plates, while cemented achromatic waveplates have the two plates glued together.
An achromatic waveplate is similar to a zero-order waveplate, but it is made from two different materials to reduce sensitivity to wavelength change.
The wavelength range for the achromatic waveplate is VIS:465-650nm; NIR:700-1000nm; IR:1200-1650.
The two plates are made from different materials, such as crystal quartz and magnesium fluoride.
The diameter of the quarter waveplate is 15.0mm with a tolerance of +0.0; -0.1 mm.
