...Learn More About: Fresnel Spots
The Fresnel fixture is designed to create a relatively
even field of light with adjustable intensity and field
size. It is most commonly used in film and television
The name comes from its Fresnel lens,
which bends the diverging rays of light emitted by the bulb
into a controlled beam of light.
This lens has the same
light-bending characteristics as a standard Plano-Convex
lens but the convex curve is compressed into jagged steps,
making it lighter and thinner so that it retains less heat.
