Achromatic Waveplate WPH225
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 the two plates are made from different materials, which allows for the retardation values to be specified at a wavelength range.
An achromatic waveplate is a type of waveplate that is made from two different materials, such as crystal quartz and magnesium fluoride.
The achromatic waveplate is designed for three different wavelength ranges: VIS (465-650nm), NIR (700-1000nm), and IR (1200-1650nm).
The two types of achromatic waveplates based on contact methods are airspaced and cemented.
The diameter of the half waveplate is 25.4mm, with a diameter tolerance of +0.0; -0.1 mm.
