Frequently Asked Questions
Projector Lens. Projector lenses magnify and focus the image onto the electron detector, typically an electron sensitive phosphor and/or a channelplate detector, producing a visible image.
Is it possible to melt projector lenses?The heat absorbed inside the lens could melt stuff and the more you stop your lens down, the more this would be a problem. The focus was quite sensitive with the proof of concept, so securing the lens to the projector well enough could be an issue.
Do all rear projection TVs have a Fresnel lens?Rear projection TV screens all have a circular Fresnel pattern on one side. A Spot Fresnel lens has a glossy smooth finish on the second side of the lens while a Linear Fresnel lens has vertical grooves that are very small, almost too small to see with the naked eye on the second side.
What is the difference between a lens and a prism?Prism lenses, however, refract light a bit differently. As a result, this produces a different result on sight and vision. Remember from science class, a prism looks like a pyramid with a base and a pointed top. Light passing through a prism will bend towards the base, while the image of the object viewed with the prism moves toward the peak.
