Holmarcâs Multiple-Order Wave Plates are made from laser grade quartz crystal. These are designed to give retardance of several full waves, plus the required fraction. These wave plates are available as mounted or unmounted and provide either half-wave or quarter-wave retardation at chosen wavelengths. All wave plates are AR coated to increase transmission at design wavelength. The retardance of multiple-order wave plate depends on temperature, wavelength, angle of incidence and degree of collimation.

So far this is a GREAT lighted magnifying glass. I love the size and the clarity of the lens as well as the placement of the light source. I also like the fact that the light does not go on automatically every time I pop out the lens for use. I have the choice to turn on the light or to leave it off. That will help to extend the battery life.
