Formula's for distances:
Reflector-Bulb= Focal point reflector
Bulb-Condensor= You can make this whatever you want it to be
Condensor-Fresnel 1= |F.Fresnel| + ( |F.Condensor|ֿ¹ - |Distance Condensor-Lamp|ֿ¹)ֿ¹
Fresnel 1-TFT= You can make this whatever you want it to be
TFT-Fresnel 2= You can make this whatever you want it to be
Triplet-Projection= Your throw distance
Fresnel 2-Triplet= ( |F.Triplet[/size]|ֿ¹ - |Distance Triplet-Projection|ֿ¹)ֿ¹ + ( |F[.Fresnel|ֿ¹ - |Distance TFT-Fresnel 2|ֿ¹)ֿ¹

Warning! In stead of bulb, take the ARC of the bulb (The mid)
ֿ¹ is taking something to the power -1. That's the same as diving 1 by something, example: 5ֿ¹ = 1÷5; Another example: 12ֿ¹ = 1÷12

With |F. ......| I mean, take the focal length of that lens.

If made these formula's, based on the basic lense formula : Fֿ¹ = Bֿ¹ + Vֿ¹ . Also, im doing this for school, and couldn't find these anywhere....
Sorry if my english isn't that well... tongue.gif
