    Default Aperture windows for projectors

    I remember people were looking for aperture windows for their projectors.
    I have recently got a new Edmunds catalog and found this
    http://www.edmundoptics.com/onlineca...productID=1919

    They have up to 10X12.
    I hired an Italian guy to do my wires. Now they look like spaghetti!

    Talking

    The Hoya daylight filters do an excellent job with highest loss in the 532nm region. All measurements were less than .03% accross the board. I have info on them somewhere....in a previous post also. The 54mm round lense I have was around $35. The ones you have located look better though as for the spec on them. Maybe next time I will try one. The Hoya's have around 40 coatings applied....plus I wanted a threaded mount

    I use the Edmunds NT48-923, > 98% transmission at 600nm. 1" X1" $12 USD.

    -edit- thats actually the same window you linked to in post #1.
    I have no complaints on their quality.
