Cooke Metrology Lens Projector

Cooke Metrology Lens Projector
Cooke Lens Test Projector
The Cooke Lens Test Projector is the
first product in the new “Cooke Metrology”
product line. It was developed for one of the
most critical and demanding aspects of cinematography: to ensure that cinema lenses are
adjusted and maintained to the highest standards possible. The Cooke Lens Test Projector functions like a slide projector, shining an
even and bright light onto a reticle. The image
is projected through the back of the lens onto
a flat white wall. This allows testers to see
how the lens handles geometric distortion of
straight lines, whether there is chromatic aberration, internal barrel flare, sharpness, where
the edges fall off (shading), if the lens breathes, etc.
Due to its innovative design and open aperture, the Cooke Lens Test Projector’s light output is the highest
of any lens projector available today, allowing the user to analyze and adjust even the fastest high speed
lenses. Cooke Metrology’s projector is so bright it can be demonstrated in daylight.
Too bright? No problem. Simply turn the dimmer knob to adjust light
output on the electronic ballast without changing color temperature. Color stability and uniform illumination across the entire field is an essential
part of Cooke’s projector design, assuring easier judgment, focus and test
repeatability on any lens.
In addition to PL-mount lenses, the projector’s interchangeable lens mount system
accommodates a variety of other mount
types like, Panavision, Canon, Nikon and
more.
The weighted lens projector base means
you can test heavy zoom lenses without
having to mount the projector onto a base
or stand, making it transportable and convenient. Safely and easily work on telephoto lenses by using the available lens
support mount with 19mm support rods.
