Does Gunaman have a 2 fresnel lens calculator? I am talking about about 2 fresnels where the Lcd is in the middle? Do we need one? For example does adding the second fresnel do anything to the length of the box? I have not received my parts yet but I want to start building the box.
Can I rely on the 1 lens calculator for distance between bulb and projection lens?
Thanks

if you split the fresnel it will increase the length of your box by the distance you put inbetween the lcd and fresnels i normaly use 2" inbetween bolth the rear and front fresnels to allow for cooling and to make sure i dont see rings on the image
