    Default Grating sources

    Hey there folks, I don't really do anything with gratings typically but have a small project I'm looking to use pattern generation gratings for. Crosshairs are pretty easy to find, but can anyone point me to a good source for grid and circle pattern generation gratings, suitable for about 50mW 520nm-650nm?

    Thanks!

    You might try contacting Wavefront Technology, and asking for samples of their diffractive optic elements, especially any Computer Generated Hologram (CGH) patterns that match what you want. They make custom patterns. Here's a link: http://www.wft.bz/lightfilms/diffractive.htm
