[QUOTE="sharp81, post: 319654, member: 16501"] hi, i am in need of help pretty quickly here.i will have to design a projector design using a fresnel lens and the projection lens.i need to find and derive the equations for the lenses and calculate the distances between the lenses and the lens and the screen. this is what i require to have : d1 - distance from the light source to the fresnel lens d2 - distance between the fresnel and the projection lens d3 - distance between the projection lens and the screen f1,f2 - focal lengths of the fresnel lens f3,f4 - focal lengths of the projection lens In my case i know the values of the focal lengths and the distance between the light source and the fresnel lens. i will have to find d2 and d3. also i need to find the net magnification factor for the light source which will be my object. any help will be greatly appreciated. harish [/QUOTE]
