instrument looks like.

Fresnel lens. The concentric rings
in the glass lens tell you this
is a Fresnel.

In
this next section we'll look at a number of different
television lights--which are actually referred to
as "instruments."
FRESNEL:
The most common studio lighting instruments are "Fresnels"
(Pronounced Freh-NELL. Never say Frez-NELL or you will
get laughed out of a job.) Fresnels come in many sizes,
but 1Ks and 2Ks are quite common.
Fresnels
have two important features. First, they have a lens
on the front of the instrument. This allows light to
be focused into a narrow beam. It's is an important
feature in television or film production. For example,
in a given scene, you might want the star to be a little
brighter than the background actors so she pops out
at the audience. With fresnels you can direct a narrow
beam onto the star's face. And because the lens on the
fresnel gives you such a tightly focused beam, no light
spills onto the secondary actors in the background.
Try doing that with your table lamp at home!
