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.
