Overhead projectors use an arrangement of lenses and mirrors to direct light through your transparency and focus the resulting image onto your screen surface. All Kindermann OHPs have optically superior, triple element lenses for outstanding image quality and even dispersion of light.
Overhead projectors fall into two categories, Transmissive and Reflective.
Transmission OHPs are where the light source (bulb) is located in the base of the machine. The light is projected up through the glass stage of the projector, through a lens in the projector head and onto a projection screen. Usually project brigher images but they tend to be larger and heavier machines and are best suited to use within one building.
Relective OHPs have the light source in the head of the unit. Light is bounced back off the reflector onto the base plate and back up through the head then out onto the screen. Not as bright as transmissive projectors but easier to use and small and lightweight enough to travel with. Ideal for presentations on the go.
