A Good Projection System?

[Murphyv310]

Hi Peter,

Interesting set.
I can imagine that the brightness is better with the larger tube. But the light losses might be a bit higher than with the Schmidt optics for the MW6-2 that Philips used in the experimental set and in the later projection sets.
The experimental set uses a special ground viewing screen ( a bit like finely sandblasted glass), but the later sets use a pressed plastic one with  pressed-in Fresnel-like lenses.
None of these Philips sets required welding goggles or sun glasses
