`
`
`Do you already have a source for such regular HWP? If not, should I contact International polarizers,
`Nitto Denko and Polatechno?

`Our rough analysis says it will reduce total illumination.
`
`I have put together achromatic retarders by hand on a bench after having read the
`key papers. I hope it doesn't come to that.

`
`
`Yes, we could. It will not perform as well as the CL material but it is something we can start with. Ying-Moh
`suggests we will see color shift on the screen and may change performance with temperature.
`
`
`This is something we will investigate.

`Hi there,
`
`
`We are having trouble getting ColorLink's attention but we are still working on it.
`
`
`Could we get started with a chromatic half wave? And then replace it with the
`proper part when available?
