Projection Fresnel Lens Linear to Spot Conversion
Projection Fresnel Lens Linear to Spot Conversion
Projection Fresnel Lens Linear to Spot Conversion: In this video, we share a process we have been perfecting for several years now. Converting a "Linear" Fresnel lens into a "Spot" Fresnel lens. Rear projection TV screens all have a circular Fresnel pattern on one side. A Spot Fresnel lens has a glo…
