Hey Everybody
I'm from Denmark and just got into this DIY Stuff, even though I've been reading for over an year on this forum 🙂
I have purchased a PSOne screen and is playing around with it, and getting.... well results 😀 But I really need to find some Fresnel's. And does anyone know where to get them in a place like Denmark??? Thinking about going to my local scholl and see if they have a spare OHP that i can rip it out of, but if they don't have one is it possible to use the ones from the 150" scam or are they to low quality
And I would like to hear from other Danes, if there are somebody out there.

another source for fresnels
If you can find a store that sells office supplies & stationary, they might have fresnel page magnifiers. Low quality page magnifiers are made from polyvinylchloride (PVC) which is soft and a bit cloudy. Good ones are acrylic which is harder and very clear.
focal length in mm = 1000/Diopters
So a 3 Diopter page magnifier is a 333 mm fl fresnel. If the power of the page magnifier is not given, then you can just measure the focal length using a distant light source (>10 meters).
