Fresnels

Altman 6" Fresnel

Strand Fresnelites

The Fresnel (pronounced fren-el) produces a soft, diffused, round wash light. It can be focused to produce a narrow beam, or spot, to a wide beam, or flood. The size of the spot or flood is determined by the distance to the subject and width of the fresnel lens. Barndoors may be added to help shape the light. The spot to flood adjustment in this theatre light is accomplished by moving the actual lamp and reflector towards or away from the lens. This adjustment is a great advantage over other fixtures because the lamp does not have to be changed to alter the beam size.
