Multiple Order Waveplates
A multiple
order Waveplate is a single piece of Laser Quality
crystal quartz, whose retardation is exactly a quarter or half a
wave. Retardation in Multi-Order Waveplates varies quickly
with wavelength. Retardation is a function of thickness and
is temperature dependent due to thermal expansion.
Multiple
Order Waveplates are not recommended in strongly
converging or diverging beams. Zero Order Waveplates offer
reduced temperature sensitivity over Multiple
Order Waveplates. When a moderate bandwidth is needed, Zero
Order or an Achromatic Waveplate is the better choice.

Dual Wavelength Waveplates (DWP)
For a given Waveplate thickness a low order Waveplate will operate as a ¼
wave, ½ wave or full wave, at two wavelengths. By careful selection of
the thickness it is possible to achieve a dual order Waveplate providing different
retardation at different wavelengths. Tower Optical provides
three standard DWP's for 532nm and 1064nm as shown in the table
below. These versions are considered standard and are in stock. Other
variations with ½ and ¼ wave are available on a custom basis. |
