Achromatic Waveplate WPH212
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 main difference between an achromatic waveplate and a zero-order waveplate is that the former is made from two different materials, while the latter is made from a single material.
An achromatic waveplate is a type of waveplate that is made from two different materials, such as crystal quartz and magnesium fluoride, to reduce sensitivity to wavelength change.
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 half waveplate is 12.7mm, with a diameter tolerance of +0.0; -0.1 mm.
