    Default Projector output window?

    Any recommendations for a source for suitable glass to use at the beam output of a RG (and eventually, blue) projector?

    Thanks!

    Hi Stuka,

    You can buy an AR coated window from Edmund Scientific Optics or similar, the quality is good and you can choose coating type and size, but the cost is expensive.

    Also, some members on this forum have (or are buying) sheets of AR coated glass which you can buy parts of.

    Finally, some users have suggested using AR filters designed for camera lenses. This looks like a good option because the coating and size is suitable for LASER projector output window, and the cost is very low! You can find these on eBay and in camera stores.

    Kind regards,
