Hi all guys I'm italian and this is my first post hi all!!
I would build a 250w + 7"liliput, yesterday I've cut the fresnel but I've a problem I can't perfect setting in the horizontal the fresnel.
When i cut the fresnels for how much is wanted to be precise they never come perfect the sides and from the moment that I must practise 4 holes to fix her to the support for the LCD I wanted to know from you if enough only centering the center of the fresnels with the center of the sketch that would correspond to the center of the LCD, because from the moment that the sides are not perfect it results me difficult setting a perfect horizontal alignment. But compose the fresnels from concentric lens, enough only that center it with the center of LCD?
